From the consumer landing page someone else linked to:
After December 16, Nexus S will be sold unlocked and carrier-independent initially through Best Buy stores in the U.S. and after December 20 at Carphone Warehouse stores in the UK.
{update} It looks like instead of selling the unlocked phone themselves, and selling carrier-locked phones in carrier-controlled retail outlets, they are using external partners to push the unlocked phone this time. At least they are learning from their mistakes. Presumably Best Buy will do some marketing for the phone (compared with the lack of marketing for the Nexus One).
They are using external partners to literally get these phones in people's hands. Consumers really want to touch phones before taking it home and Google seems to have taken this lesson to heart. Also having an army of blueshirts to provide setup help at purchase will make the less technically savvy happy campers.
Buying the Nexus One without feeling one first definitely was a little weird for me, but the return policy assuaged my misgivings.
