I would guess more than a few. Considering the number of cpu/gutted/slow build teams this year all the way to the top, I predict that anyone winning 1st round in the playoffs will move up.
I suppose, actually, if someone were ambitious enough to look they could calculate exactly how many teams should move up based on total cupcake teams to move down.
Unfortunately i'm not that ambitious

It'll be for the best. At least for next season as long as we don't have another huge cupcakeification at the upper levels again. It'll be rougher though with, hopefully, increased competition.
