Xbox games are region locked, but cheaper second hand price.
PS3 games are of higher price second hand, but it also means higher resell value for ppl who buys game, finish quickly and sell afterwards.

imo now is not the time to buy console.Next year got Wii U and next gen Xbox is expected to be announced on January at CES.
New consoles would mean price cut for old ones.
You buy now will guarantee millions of regrets.
