From what I understand, is that this Wally West wasn't from New Earth, but was stuck in the Speed Force for some reason, and he was able to witness the first Crisis, Infinite Crisis, etc. And for whatever reason, Dr. M created Prime Earth by altering the universe during Flashpoint and stole ten years for memories from the DC Characters, thus making them forget Wally.

As for Donna, I just hope they retconn her New 52 origin somehow. I don't even care how, they could retconn the whole Finch run and I'd be happy.
