I don't think Paizo will do anything differently.
The question is more of "how will WotC support 5E?"
The official adventures for 4E were widely panned (though there were a few exceptions, IIRC), so whether or not 5E succeeds will depend on how capable WotC is with support.
I don't think the corporate culture at WotC will allow for the quality and type of product necessary to sustain 5E.
I agree although I don't think it's the corporate culture: I just don't think they have any good adventure authors.
WotC does have a tendency to promote good writers into positions where they no longer write. Promoted to incompetence as it was.I agree although I don't think it's the corporate culture: I just don't think they have any good adventure authors.
Chris Perkins is a great adventure author but he seems to have a lot of management responsibility which obviously precludes him from writing much.
Bruce Cordell used to be fantastic (2E's Gates of Firestorm Peak and The Shattered Circle are both classics, IMO) but the last good adventure he wrote was Sunless Citadel.
Unfortunately, they retrenched Rich Baker whom even Chris Perkins called the best of WotC's adventure writers.
Anyway, after Next is released they will all be worried about being retrenched so support products won't exactly be on their minds.
