Saw this over at Team Xbox. Apparently Wal-Mart employees have leaked the Xbox 360's release date and US Dollar price.
According to the unofficial leak (that's why it's a leak. Who knew), the Xbox 360 will release on November 4th and sell for $299.00 US.
I expect I'll end up snagging on, though not at launch. Most likely during their second wave of titles in late spring/early summer when it's expected Halo 3 and Jade Empire 2 will be released.
