Well, Insidemacgames does have C&C Tiberium listed with a release date of July 7th. I get the feeling both BF2142 and C&C will be released on the 31st of July.
Probably a placeholder on IMG's part.
But, I think EA is going to miss July. Just my gut feeling. As I stated in that other EA thread, I just don't know how committed EA is to the Mac platform, and I wonder if they even have a Mac support group ready.
