Since we're supposed to be discussing Brawl stages, I'll give my take:
Battlefield: Random, same as in melee, the glitchy edges might be gone.
Lylat Cruise: Random, Seems a lot like Battlefield.
Yoshi's Strory: I hope the clouds are on a timer. Random or CP, though I think Random
Delfino Plaza: Like Mute city, but without cars. The walk off sides aren't bad since there's no waveshining. Counterpick
Skyworld: counterpick, because of hyrule teching, and the overall weirdness.
Smashville: Very Balanced, Random
Eldin: Banned, hazards seem like a big deal
WarioWare: The whole stage is about randomness and randomness = bad
PS 2: From what I hear, there are some hazards, so maybe counterpick
Halberd: From Gimpyfish's report, the hazards aren't that big of a deal and it could be counterpick
Shadow Moses Island: I have no Idea, but I would go for banned because of the walls, and hazards (there are some, right?)
New Pork City: Banned, Camping squared.
Picto Chat: Banned, seems like a lot of hazards
The Summit: Looks like a counterpick stage to me, as it moves in cycles and not randomly. Looks sorta like Dream Cruise or whatever it's called in melee.
Just my 2 cents.
