They're talking about Medal of Honor, not Assassin's Creed.
But yes, EA is definitely doing it on purpose. The first one did not get very good reviews(and from what I played in the beta, neither will this one), so I guess they're trying to keep reviews out of the picture for the first week of sales.
I'm not so sure this is the reason. I think it more has the do with the massive day 1 patch for MoH: Warfighter. which was most likely put in to "complete" the game -> http://www.xbox360ac...nely-Large.html
They probably didn't want reviews until the patch was out because the game was shipped incomplete (hence the extensive day 1 patch), now the reason for the "incompleteness" in the first place could either be:
A) Because the game needed to go gold early enough to meet the release date, giving EA a claim on the FPS market until BlOps 2 comes out a month later, cause let's face it, very few people are going to be playing Warfighter when BlOps 2 is finally released, just from hype alone. MoH doesn't have the fanbase like Battlefield does and this is EA's only military-FPS this holiday.
or B) They've been tireless in working on fixes for bugs reported in the beta, and wanted to roll them out ASAP.
Considering how recently the beta started and ended though, and knowing EA's usual tactics, it's most likely A, which is you know, bullshit.
