Crysis 2 only DX9 - DX11 will be "later" with an update

[Pontos]

For me it pretty much points everything towards that no dx11 patch will come. Instead we get the DLC of 4 new MP maps for probably 15$ (that where already in the leaked beta)

Hold on there. Are you saying that MP maps that were in the beta-but-almost-final leaked version are NOT in the retail one?

If they really end up showing up in a DLC as you say, then i at least hope for a massive outcry in the whole gaming community (Not only the PC side)...
It would be the first time in history that a post-release (non Day-0) DLC has content that was finished before the actual game's release and simply got in hold for extra profit.
Most of the time is stuff that didn't get finished on time, or got no real incentive to get finished on time at all (In fact, incentive to the contrary, heh)

srsly I don't know a game that had client side settings for MP since the original quake... and even there many of them got locked later and replaced by server side cvars...

The whole MP is a disaster. The CD-Key you get with the game? That only gets checked Client side, and has no real impact in the MP mode. You can put anything you want as CD-Key and join any server without a single issue.
