User blog comment:JakePT/ME3 Info Blitz Begins in April/@comment-1221773-20110331033153/@comment-1691295-20110331075614

Apparently Modern Warfare 3 info is coming in April as well, so that might be what Game Informer is covering, and PSM3 might have the ME3 exclusive (they do say they have the exclusive, but explicitly mention the PS3 version only). GI's cover reveal should be within the next 7 days, so we'll know by then.
