Okay, I haven't the time to read all of these answers, but I read most of them, so if this was already said, forgive me.
Anyways, I can actually see this happen, because like George Harrison said, All Things Must Pass, so I mean, I personally don't think they have to much of a grudge left to hold. Roger is more of the ego-maniac from what I've read about this argument, but we honestly don't know what's going on in their real lives. They could be calling eachother right now and talking to eachother. I read in a recent David Gilmour interview that in 2000 he actually saw Roger at a bar, said "Hello", and Roger took his boys and walked off....but anyways..

Could I see a re-group happening? Unlikely. First off, I'm not saying this because Roger is an ego-maniac or some other obscure thing like that. I think it's personally because all the members have finally gone all their seperate ways, and I'm sure Roger is having fun with his current band that comes along with him on tours, as well as writing his own music. David himself has said that he really doesn't even want to go up in front of an audience and perform anymore, much less record an album, he just doesn't have the desire anymore; he's made his mark. However, this is just my opinion, and I could be very wrong indeed, but if Pink Floyd does make another album, with or without Roger, it will be good, guaranteed. And don't mock The Division Bell, I don't care what anyone says, that is a great album.
