If you look at the track record, they treat the current generation Nexus very well, and older models less so. Forget about ICS, the Nexus One didn't get Gingerbread for over 4 months after it was released. It did, however, get Froyo almost instantly, just like the Galaxy Nexus recently got JB almost instantly.
