This conversation reminds me of the continents song we learned back in kindergarten. Yes man, there are 7 (unless my kindergarten teacher was wrong :P), though I guess some decide to combine landmasses or whatever, but the answer has always been 7 for me.
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).
