I think none of the above, so i have not voted. Pathfinder has a solid entrenched position and Paizo does not make money from selling rulesets but subscriptions to adventure material. So D&D Next is very likely to outsell Pathfinder, this is as much from the fact that Pathfinder has pretty much sold a copy to anyone that wants to buy one as anything else.
What we really don't know going forward what is WotC's business plan this time around. Last two iterations of D&D it was obviously to produce as many rule supplements that the market could bear and churn them out for as long as possible, lather, rinse and repeat. Now, we know this eventually lead to a customer backlash and the emergence of Pathfinder is part of that.
My guess is that the rule suplements will be relatively light in this edition, enough to maintain interest and buzz, may be a couple of books per year and setting material and adventures delivered via online Dungeon and Dragon with the bulk of money from the D&D brand to be obtained via other products.
Namely boardgames, platform and pc games, movies, books, comics and so forth.
There may be an expansion of Encounters via social media and online gaming but it will follow the enabling technology, no more grandiose attempts to lead online development.
