Keeping HHH on Raw leaves the option of the Orton vs HHH match still in the works for later
(Still I was shocked when he got drafted in the first place)
As for the ECW thing, i'm betting Paul Heyman gets a role as a manger for a while just to leave the door open for the ECW spin off later. Everything I've read so far says the ECW idea is still on the back burner and Vince can't choose where he wants to have the spin off or not.
