Do we have any idea how much you'll be able to get if you sell these on ebay around Black Friday?
What we don't know yet is the real interest in WiiU. It might just be a PS3 thing, where everyone ran out to preorder it JUST to Ebay it. Then the only profit you could really obtain was on day 1 of the sales, by next week people either lost $ on selling it or only broke even due to Ebay/Paypal fees. Then again, it could turn into the Wii situation where people actually want the console and lots of $ could be had..
I predict it will be more like the PS3 because the mass market casual players have little interest in it, unlike the Wii. Mass market will be focused on the Ipad Mini, etc. Of course this also depends on how many consoles Nintendo can provide, the Nintendo hard core gamers will all want to buy it and if the initial shipment is super low, then a profit could still be had.
