Can I trade my black xbox 360 for a ps3 at gamestop?

I'm just really tired of xbox live. I don't want to pay for xbox live just to watch a movie on netflix.

I have a couple games too:
Kinnect animals
Minecraft (downloaded)
Kinnect Adventures
And
A Kinnect Japanese dancing game
I think thats all the games I have.

So can I trade these games plus my black xbox 360 for a ps3?

Also If I can trade for a ps3 can I download Minecraft in the store or something?

Added (1). @The Shadow, How much money should I add with the trade?

Yes you can trade it for other game no problem.

Yes, but not a straight across trade - you'll need to add some cash on top probably
yes, you can download minecraft for ps3, just look in the playstation store and have enough money in your psn account to pay for it
if you get the ps3 I recommend you also buy a plus membership for one year, you'll get a dozen free games day one, new free games monthly and deep discounts on psn games ( as much as 75% off the regular price )
