Why not bring it up? The chap wanted to say "goodbye" and that's it. I bet he wishes he hadn't bothered now.
I have to admit, it seems folks are having a field day with this. I could understand it if it were the case that Hyperion Entertainment had turned round and said "so long and thanks for all the fish" but that's not what has happened. Well, at least not yet anyway though I'm sure some folk still live in hope.
