Hey Hong! Long time, no see!
I think the point would be that the rules could be extremely complex, and yet totally transparent to the players. You could achieve a rules-lite experience at the table while having a ridiculously involved system behind it.
And the reason I think this is crucial kinda played out on message boards after the D&D game day. Now I ran the adventure in like 3-4 hours tops. Others took seven hours to run three combats and one skill challenge.
D&D cannot survive that. Not if it's "back to the dungeon". If the game is not going to focus highly on story, and it is back to the dungeon (and to be honest, many of the adventurers I've seen and several I've run have followed this mantra), the game cannot thrive long term under those conditions. (In my opnion of course.)
The game has to flow much quicker. Being able to double tap your character's power on your application and having the results sent straight to the DM and instantly deducted from the monster's hit points etc..., even if it's not as fast as a true MMO, has to be faster.
And hey, think of all the neat little sound effects that could be marketed for the different powers. "Man, your raging thunderstrike sounds awesome! Where can I download that."
