You mean they would buy themselves from EA, like Activision did? Because EA's not giving up the BioWare name for free. And BioWare doesn't have that kind of cash.
This is the second time they are trying to make a big online thing, after SWTOR. While that didn't flop as such, it seems EA had far higher expectations for it, making if effectively a failure. EA wouldn't be pushing for something like that if they were content with the sales from Dragon Age and Mass Effect alone, especially after Andromeda.
