Hmm... my immediate reaction is that this screws with the timeline of the origin of Baator, and we've now had a variation of the origin of that plane for pretty much every book that has come out since the late 90's. The Abyss has had more stability than the plane of manifest LE, which is unfortunate.
The twisted little origin for gelugons might be a really nifty idea, but we'll see how the fluff handles this. I can be won over on this one. 'loth origin gelugons, bound by contract and chaffing against it. This could really be developed into some cool stuff. EDIT: 10 minutes later, I'm digging this one.
Merging succubi and erinyes is a mistake. A really bad mistake. I can't immediately see how to reconcile this with the material already out there, and even produced in the past year. Hmm. Jacobs did some really awesome material with Malcanthet and her rivals, and this change really makes moving them forward into 4th difficult, unless we want to have succubi/erinyes populating both Baator and the Abyss, having split in an ancient ideological schism (or the CE ones having been perverted by X Abyssal lord, obyrith, etc). The in-game rationalization here needs to be amazing or else this change may really, really present difficulties.
