I had assumed the new BigAss center was going to be just like that, sort of a W(T^M)W. I would have been really happy with one of those, although of course I expect to be even happier with my VP180 if I can pry it loose from Purolator's "we only work on weekdays" hands
The side ports seem like a great idea. They would be a problem in a conventional TV stand so you wouldn't want to put them on all the center models, but anything too big for a TV stand would be fantastic with side ports. Placement instructions normally suggest that the center should be a bit closer to the wall than the mains, in order to give a consistent distance to the listener, which implies the center needs to be real cozy with the wall.
