I'd still go for a j Tag, Those are simply rumors and even if they are true the next box won't be out until mid 2013 and then the first year or two are pretty lackluster for new consoles.The 360 still has a couple of good years left.Remember titles like GOW 2 that came out on the PS2 a year after the PS3 was released? Plus you also have the games that came out in 2011 to play.
The latest LT 3.0 needs you to use full burns or something which will cost you about 300 RS ore more per disc in it's current state.
