Inevitability is a bitch. The fact they rolled out like 5 albums after Be Here Now is testament to how much they did it for the fans more than anything, they've largely only acknowledged each other on tours since that era.
Oh, by the way, the money as well obviously, but Noel will still be to draw pretty damn well on his own, Liam and the others, if he's retarded enough to continue Oasis, will do ok for a bit, but it'll fail. He's the one that needed Oasis more.
