Google getting cozy with Verizon and Sprint for the Gphone?

The Gphone rumors have been heating up lately, and things seems like they're about to come to a boil. The Wall Street Journal, not generally known for wild rumor-mongering, is reporting that Google is in "advanced talks" with Verizon and Sprint and has made "significant progress" with T-Mobile, with an announcement of some kind due within two weeks. The news sent Google stock past $700 today, although it's still not clear if Google is simply developing its own software or going all out and doing an entire handset. Either way, it looks like Google's getting ready to make a move sometime soon, and with the amount of chatter we're hearing, it's going to be a big one.
