What I'm curious to see are the Caster PrE's.
In particular, sorcerer. It sounds as though the sorcerer PrE's are simply some time of elemental/dps specialty lines, which would basically suck, making sorcs only choices b/w different DPS specialties.
Caster burst damage is pretty negated right now in high content, and I can't imagine it changing back any time soon. Only giving sorcs DPS PrE's would not be fun.
