Those saying about "it might be just the Austin studio" seem to be overlooking the whole "Zeschuck and Muzyka might leave" aspect of this. Thats pretty huge for the whole of Bioware.
Honestly wouldn't be surprised though. Look at their past three big releases, focussing on how people have reacted to each:
DA2 - Was criticised heavily by many people for being a disappointment. The general feeling was that it was unimpressive compared to Origins and wasn't what many people wanted. Possible EA influence into making it more action-based being part of that. Consumer backlash and disappointment. Didn't live up to expectations.
ME3 - Do I even need to mention the car crash of an ending here? Everyone should know by now the criticism levelled at it but in short the general feeling was that it was poorly written, poorly thought out and felt rushed. Rumours abound of EA influence again there in rushing the deadline. Again, consumer backlash and disappointment (on a comparatively massive scale this time). And again, didn't live up to expectations.
SW:TOR - The alleged WoW killer that is now going F2P and haemorrhaging players. Hardly a disaster, but still massively underperforming from what was predicted. In short, overhyped. A third time, didn't live up to expectations.
I mean...looked at objectively there have been problems with all three of their last three major releases. Regardless of what any individual person felt about them there were huge numbers of people disappointed and/or unimpressed with each. One has to wonder if perhaps the masters at EA have decided they need to do something about it to try and "fix the problem"; not realising that the biggest part of the problem is arguably EA itself.
