自分は現状ではM3を買うことはないのですが...
F80/82 次期M3/M4のエンジンについていろいろな噂があり，最近BimmerFileでは直６になるらしい，という情報が出ていました．
その後いろいろ見てみると，昨年の１２月に，F30POSTにこんな情報が投稿されていたようです．ドイツ語での投稿を誰かが英訳したものです．たぶんこれがBimmerFileの元ネタっぽいですね．テキトーですが訳してみました(間違ってたらすいません)．

I have a very close relationship to the M-GmbH and as of Monday in fact the V6 was the favorite and was high on the development list.
Unfortunately, on Monday the Board decided to stop the V6 project and go onwards with the R6 (I6?) ....
It is and was clear that the V6 can do everything better!
It is balanced, offers the potential for better development, better response, etc. ..
The power output was originally advised to be 470PS, with driver's package even 500PS ...
The only drawback: the cost!
And this is exactly why the project was ended and replaced by the R6 (I6?).
It is now a booger pimped 335i! Thus, the power will be 420 horsepower max and the M3 will offer only slightly better performance because of the slightly lower weight compared to the E90.
Now everyone needs decide for themselves what they want ... I will personally shell out no more than € 25,000 ($34000) for a 335i pimped, because what benefits will the M3 offer now compared to a 335i?
The crappy optics? I don't necessarily need them...
The DCT? That will also be available on the F30 335i ...
The adaptive suspension? The F30 335i has that also now ...
The performance? Give any tuner $1,000 there as well ...
... and if it [the tune] blows the engine? Yes... it's just $20,000 for a new one - still cheaper than an M3.
Anyway, I'm not willing to buy large-scale production technology at inflated prices.
An M has always been something special and its price would better be worth it somewhere!
But under the expected circumstances, I'll buy a C63 ...
kueks29はM GmbHとは非常に親しい関係にある（ために情報を得ている）．
MとしてはV6が最もいいと考えていて，開発リストの上位にあった．
しかし取締役会により，V6の開発は停止された．
M GmbHはV6のほうがバランスが良く，ポテンシャルが高いと考えていた．
出力は470ps，仕様によっては500psが考えられていた．
唯一の欠点は，コスト！
今後は335iベースで開発される．出力は420ps位でE90よりは軽量化される．
（中略）
これならF30 335iを買ってチューンした方が安い．自分ならC63を買う...
別のコメントでは，
What are you talking about ? I6 ? What was the reliable source about the new M3 using I6 engine. Everybody is talking about the V6 turbo, are you dreaming ?
という問いに対して，
Unfortunately, I no longer dream.
There was a V6 engine, the engine was internally called Apollo. This engine was already fairly close to serial production, but production costs have his neck broken.
Because in the first place in the specifications was to reduce the weight by about 200 kg compared with the series. The only costs money and the vehicle must remain somewhere afterwards in an affordable and financially interesting framework for the customer.
Therefore, we changed the strategy and swung around on a modified I6 based on the N55.
Whether you scold me now or in China is a rice-bag it to anyone interested in Garching.
Fact: The F80 gets an inline six-cylinder 3.3-liter, 450 hp and 640 Nm.
Whether you like it or not ...
V6エンジンはあり，コードネームはApolloと呼ばれていた．すでに生産にかなり近い状態だったが，コストによって凍結された．新型ではスペック的に通常モデルよりも200kgの軽量化が謳われており，（そちらにコストがかかって，そこにV6を新規に開発，搭載することは）顧客の望む価格帯に納まるコストではなかった．このためN55ベースでの開発となった．F80 M3は3.3L直６で，450ps, 640Nmとなる．

Last night I was at the presentation of the F30. Among other guests was also a current DTM driver.
But someone from the M-GmbH. Of course I asked for the new M3 engine and got on just a blink.
When I asked what that would mean, I was told:
"are at the last time penetrated to a lot of information to the outside, so radical that was-at least invoked inline-6 official! also means the inline-6 old BMW history. will Nonetheless, there is no inline-6, but a V6! The engine is derived from the M5, has 3.3 liter capacity and will introduce a new generation of M engines! "
昨夜はF30の発表現場にいた．DTMドライバーやMの関係者もいた．もちろんM GmbHの関係者に次期M3のエンジンについて聞いてみたら，まばたきをした（別の意味の気がします．どなたか教えて下さい）．それがどんな意味か聞いてみると，
「ついに多くの情報が外部に漏れてしまった．それも徹底的にー少なくとも直６が公になった！でも，直６はもうBMWの過去のものだ．いずれにしろ，将来的には直６はないー3.3LV6だ！これはM5のエンジンから派生したもので，新しい世代のMエンジンになるだろう」
As I said: The last information said very clearly: It is an inline-6!
私が言ったように，エンジンは直６！
The last night sounded very authentic and the present DTM drivers said later in a small circle just telling: "BMW has been the tradition in motor sports and also in the DTM One reason for the decision to the DTM the possibility of a promotional message from the motor sport! transferred to the road! from season 2014 this will converge, although the V8 engine technically no longer be used! "
DTMドライバー曰く，「BMWはモータースポーツの伝統であり続けてきた．DTMに参戦する理由の一つはモータースポーツからメッセージでもある．2014年からはV8は使えなくなるんだ．」
（Ｍ３でＶ８はないよ，だとするとモータースポーツで使うのはV6なんだよ，ということを暗示？）
Furthermore, it was rumored in a similar form of a re-entry into Formula 1, because the engine would correspond to the concept of the next M3 ...
さらに，F1にもう一度参戦することも噂されていた．なぜなら，レギュレーション変更でF1はＶ６ターボになり，次期M3のコンセプトと合致するから．
Ladies and gentlemen, I think we all are a huge rip-mounted and are contrary to all protestations to the current M-GmbH and exclamations of insiders still see a V6 ...
この文，よく分かりません．現在のMの主張や，未だにV6のことを考えている内部の人たちとは，自分たちは相容れない，ということでしょうかね．
ちなみに，もしＶ６だった場合の新型の性能データまで出てますね（ホントかどうか知りませんが...）

これらの情報が正しければ，次の次のＭ３はV6になり，さらにBMWからいずれ直６は消えるかもしれない，と．
さて，真相はいかに....
P.S.ちなみにこれら情報はF30postの投稿されていたもので，情報の正確性については私は何も責任を持ちませんので，あしからず．
以前はCD屋に行って試聴して買っていたのですが，最近はなかなかいけなくて，Youtubeで偶然見つけたあと，iTunes Storeで試聴してＡmazonで購入，というパターンがほとんど．ちなみにダウンロードではなくて，未だにCD派です．
自分は現状ではM3を買うことはないのですが...
