Leave out the trollness in this free and open speculation about what might be in Wuu. There's no prize for being right, not penalty for being wrong, and as long as there's sound reasoning behind every opinion it should be accepted.Keep posting rumors until it come true.....or not.
For the 50% figure to be true, well, I guess 50% more RAM goes a long way towards that. 50% more RAM, and a reasonable increase in processing grunt, and I can see how that'd be called 50% better by some folk. It'd also point to Nintendo's current SDK setup being poor given what was on show.
