You can't do "market research" if the market doesn't exist, and Nintendo's current success is based on creating new markets. So if EA are basing their business on market research, it would be proof that they haven't learned their lesson.
I don't think there's anything wrong with releasing Dead Space as an on-rails game, or doing a sequel to Boom Blox, or making Wii the lead version for games like Tiger Woods and Harry Potter, but none of that is going to create the 5 or 10 million seller that EA used to create with some regularity and which they desperately need right now. The only thing they've announced which could be something of substance is EA Sports Active. There's plenty of room for it to differentiate from and improve upon Wii Fit, and everything else out there seems a little cheap right now.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
Satoru Iwata, Nintendo President. Only slightly paraphrased.
