I read the blog, it seems to me that they did not compromise the PC version. They just limited the console versions to 24 MP since they just didn't have the power to run 64 and still maintain the graphics and game play that DICE thinks is acceptable. DICE wanted the console version to look as good as possible with it's limited power and have it similar to the PC. Where the PC ver will be better is the higher res that can be used and prob some other stuff like AA and motion blur and other DX11 eye candy. Some testers have stated that even though its was an alpha the game play and graphics are better then any other FPS out (even better then the early MW3 tests). So don't rush to a conclusion, just wait for the game to come out. Just IMO.

"Isn't it refreshing to see a major game development studio putting PC gamers first? In an interview with German website GameZone.de, the guys at EA DICE have detailed some of the compromises they're making to squeeze Battlefield 3's multiplayer onto consoles—and it sounds like only PC players will enjoy a full, unhindered multiplayer experience.
According to the translation provided by CVG, DICE's Patrick Bach says the Xbox 360 and PlayStation 3 versions of Battlefield 3 will have more "compact" multiplayer maps with support for only up to 24 players, down from 64 players for the PC version. Supporting the same number of players on consoles would have purportedly entailed scaling down graphics fidelity, toning down map destructibility, and removing vehicles—none compromises the developers wanted to make.
Bach explains, "We would love to do 64 players on console but then we would have to cut away so much; people would get very upset that it looked worse, played worse and wasn't as fun as the PC version."
Of course, fun is what it's all about, and DICE is working hard to make the game equally enjoyable across all platforms. "Our aim is to give the player the exact same experience and not try to dumb down the console version," Bach says. "We want to create the same experience for PC as for consoles." Still, it sounds like PC gamers will get a bigger slice of delicious Battlefield 3 multiplayer than their console brethren."
