AFAIK EA puts an embargo on all their titles, major or not. I have no doubt DAII will have, at the very least, solid reviews. Most previews/impressions of the demo, for example, were rather gushing in tone.
Apparently they do it for a lot of games, but Dead Space 2 for example didn't have an embargo until release day. Another example of dishonest behavior by EA IMO. It's sickening how the gaming "press" and the publishers collaborate to mislead the consumer, I haven't seen the mention of the embargo on a single gaming site. Edit: Previews are normally a lot more gushing than the reviews, that's another example of the collaboration.
