2TB Bundle is ahead of the PS4. XB1 with 500GB is already rising as well. I expect the 1TB bundle to also blast in soon. Expect a very strong August from Microsoft.
Made a bet with LipeJJ and HylianYoshi that the XB1 will reach 30 million before Wii U reaches 15 million. Loser has to get avatar picked by winner for 6 months (or if I lose, either 6 months avatar control for both Lipe and Hylian, or my patrick avatar comes back forever).
