Halo: Reach might be decent. Its future installments of Halo that I worry about, since they won't be made by Bungie.
There are only a couple IPs that ever truly survived "the handoff", that I can recall -- namely Legacy of Kain (Crystal Dynamics took it from Silicon Knights), and Tomb Raider (again Crystal Dynamics.. took it from Core Design).
Every other major IP handoff I can think of went downhill, and fast.
