Assuming the result will be the same assumes they have neither the ability or the intention of producing a substantially different work. I would argue the facts suggest otherwise on both points. It's readily apparent that WotC's design philosophy has shifted substantially over the last 10 years, as they seek to both correct previous mistakes and respond to the change in player demographics.
Faulty assumptions can be corrected and errors in judgment can be learning experiences. I have a higher opinion of those three than to believe they'll still be making the same mistakes a decade later.
This is where folks always get into trouble. Specific designers and their potential shortcomings are named. Someone responds to say that it's "readily apparent" that "WotC's" design philosophy has shifted substantially, as if it's the corporation's charter in Delaware that's writing D&D books. No one ever gets specific by referencing the designers' actual work.
Where are we supposed to see this alleged substantial shift in the quality of DM support from Crawford, Perkins, and Wyatt over the past ten years? How have recent WotC books shown substantial improvement in helping DMs produce good play at the table? Where are the innovating in presentation? I see a lot of that in other third-part arenas, but where are we seeing it from Crawford, Perkins, or Wyatt?
EDIT: I don't think it's controversial to suggest that Crawford/Perkins/Wyatt wouldn't be in most folk's Top 5 DMing Advice recommendations. Sly Flourish, Alphastream, How To Be A Great GM, Matt Colville, The Alexandrian, Dungeon Dudes, and many others would probably edge out those WotC guys. Whatever their strengths are, DMing advice isn't among them.
I concede that Wyatt's name's on the 4e DMGs and those are well-regarded, including by me. Crawford and Perkins are
not listed and they're in charge of 1D&D. So whatever Wyatt might try to contribute will have to run through them, which doesn't inspire much confidence.
