Also EA could just make ports of their annual sport franchises from x360/Ps3 to WiiU. Ubisoft told us that these ports can cost around 1-1.5 mln USD. Then even the sales of 100 000 games on WiiU would bring some profit to EA. Since they not going this way, it seems the reasons are not money but smth else...
Well, none of their games have actually broken 100,000 so at the moment each title is still in the red if your figures are correct. That in itself is astonishing considering the porting costs are relatively cheap so it would make perfect business sense to jump out now for a company trying to get back to profitability.
Not saying there couldn't be something else, but the business case is a strong one.
