You can check it out, here.  There's an article and a video, there. Video will give you a better idea of what they're going for, though. Though it looks pretty silly when it's overused like it is in these videos, the big addition so far is weapon interaction. Any move can put your opponent through a table, and you can finally do some of the crazy things you used to see in Money in the Bank matches, including leaning ladders on the ropes to dive in or out and doing your finisher off the ladder. The tables still break kinda' oddly, but look at where they break. Exactly where the contact was made. And it looks like table parts stay in the ring much longer. Hopefully things like chairs don't break, now. It was a useless 'feature'. Also, the chairs are finally black and not bright blue. =P
