So...what can bioware do? They are 'looking at feedback' What can come from the feedback that can change peoples reactions towards bioware and Mass Effect 3? Retcon, epilogue, totally not mention and ignore it in DLC?
There hasn't been any indication that they will actually do anything. Most of things they have done are just PR reacting to a shit storm way bigger then what they were expecting.
If you want, you can read a little analysis of the PR response in this thread at BSN.
Basically, it appears they just trying to keep their fans "waiting for something" until it blows over. We will possible find out more at the PAX panel happening soon (in two weeks? I'm not sure of the date).
I'm not getting my hopes up. Any DLC to retcon the ending would cost money and take time, and we all know how EA is generous with these things. Also, it would require Bioware to flat out admit they screw-up, something I don't think they ever did.
