[citation]The PS3 CAN do AA, but because its "RSX" is simply a cut-rate G71, it can't do AA+HDR, and the developers have always chosen HDR.[/citation]
I'm not sure where you're getting your facts, but the RSX is not "simply a cut-rate G71." It's not the same exact chip as some minor modifications were made at Sony's request - not to mention the RSX is designed to make use of the significantly higher bus bandwidth available on the PS3 as compared to the first-gen PCIe bus of that time. But even if it were exactly the same as a PC-variant G71, those have no problems running HDR and MSAA simultaneously. Take FF13 for example. The mode it runs at on the PS3 is 1280x720 at 2X MSAA. And that game does make use of HDR lighting as well. (

When that first came out, only ATI cards could run MSAA with HDR, whereas only one or the other could be enabled with an Nvidia product. But they eventually got MSAA+HDR working on Nvidia within a few patches. And the Geforce 7800 series (G70, G71, etc) were the predominant cards from Nvidia at that time.
I'm not a fanboy for any one platform. I own both a PC and a PS3 and own the original Crysis along with Far Cry and Far Cry 2 on PC. Crysis 2 will undoubtedly look best on current-gen gaming hardware compared to console hardware that is 5 years old.
That being said, I've been impressed with what they've been able to do with the PS3 as of late - using the additional Cell cores to add graphical features and effects and quality of those effects far beyond what the RSX alone is capable of rendering (such as in Uncharted 2). Saying that the PS3 is limited to DX9 level effects is not entirely correct, especially if Crytek is stating that they are making full use of all the hardware on each respective platform. If they get Crysis 2 on the PS3 running and looking anywhere near as well as Uncharted 2, I'll be impressed.
From a gameplay perspective however, FPS games typically are most enjoyable on a PC, as full mouse and keyboard support and and and actual server browser for online play are hard to do without (if you are used to having them available).
