yeah...hmmm I am not so sure you will be able to turn profits so easily this go around. I sold 2 PS3's for over a grand at launch and it was fantastic.
Going by the 3 latest console/portable releases, (3DS, VITA, and WiiU), none of these were worth anything more via Ebay on release day. I will preorder 1 extra of each just in case but I dont think we will be able to profit more than $100 per system.
Once the companies actually announce that they are in fact releasing something this year, then I would look at Bestbuy/Gamestop/Amazon. For meow...nobody knows anything about them.
