If I was working on a new Medal of Honour or Battlefield, or even The Sims, you'd have to shoot me in both kneecaps before I'd consider taking my name off a game that could boost my career.
All you're going to get to make these games are either raw flash kiddies, or you have to take over a company with experience in making money on flash games. IMO I'm not surprised one bit, buying a company like Playfish was EA's only move to make.
Getting that right, IMO, is both harder and more important than having games with high production quality.
Pogo has what, 10MM pageviews per month? Playfish has games with more monthly players than that.
Also, the winners in social gaming don't require EA's strengths, which revolve around branding and production quality.
