Well just can't understand why MS want to make things region locked. It sells less, it turns away its die hard fans in many countries. For exclusiveness they can lock it for the first month or two, then open for public after that, region-locking a dlc forever just doesn't make sense.

I spent more time on PSN now to be honest, it has a 4-slot sharing, most DLC are not region locked, and surprisingly it works really well in most mp games, lagging are very minimal now and connection endurance/performance are almost identical to Live. But i will still hop-on to Live tho for games like GOW3, i probably won't renew Live membership if there is no apparent good exclusive MP game supporting it.
