Nope I never bought a Wii until two years after. Not for me for my siblings but when I lived with them I swear I used that thing more than them.
If that 360 got you $1700 I would love to see what the ps4 unopened with warchdogs, bf4, and cod ghost could reel in. I would be able to pay mine off and buy 2 more, one for me and another for my younger brother who probably won't get one unless my dad or I buy it for him.
360 was the pinnacle of reselling consoles. when ps3 came out so many people bought them JUST to flip them that the market crashed for it. i mean they still sold for a good amount, don't get me wrong, but nowhere near like the 360's did. i had 2 ps3's and ended up just returning them for that reason.
wii's on the other hand made a lot of money for people. i personally didn't get in on it, but i know people who did. it was the hype around it + the shortage of them that drove prices up. it was pretty easy to double your money on a wii initially.
i don't think that ps4 and x1 are going to be NEARLY as profitable on the aftermarket. the fact that 2 consoles are launching nearly at the same time, plus it seems they were able to start producing them much earlier, means that there will be less shortages and demand IMO. but hey it doesn't hurt to try it and just return it if you can't flip em. that is probably why i'm going to keep my ps4 preorder from amazon and see if i can flip it, and if not, just return it.
and selling bundles won't net you anything more, and would probably drive the overall profit down. games aren't what are scarce, consoles are.
