The prior two Nexus phones had this property. Zero crapware, plus no boot-locking, so you could rebuild the whole phone from source code, if you wanted, and install it without being required to "jailbreak" your phone.

For the current Galaxy Nexus, this appears to be the case, at least for the GSM version they're selling everywhere except the U.S. It's less clear what's up with the U.S. CDMA version. There's some screenshot evidence to say that it comes with a handful of Verizon apps, but it's presumably still a proper dev phone, so it should be relatively painless to return to pristine form, if you really want.

Also, for the record, the two previous Nexus phones weren't exactly made "to Google's specifications." My understanding is that they were more the case that they had these in the works and Google came along and said "gee, let's make that be the next Google phone." The current Galaxy Nexus appears to have been more of a direct collaboration between Google and Samsung, at least based on a handful of sketchy stories I've read. This is almost certainly a good thing.
