The problem with that is this: WotC wants/needs to break compatibility with existing VTTs, especially Foundry VTT. They can't do that if the game is as similar to 5e as you think it will be. Foundry is already out under the 1.0a. Foundry does not need to do JACK. If 6e is close enough? It will still work.I think this is the $1B question. Based on what we've see so far, this is very much a Revised 5E/5.5E than a 6E, so I think that regardless of the nonsense concerning the OGL, it will be at the very least a moderate success. If it were to completely fail, I think this would be because of the OGL battle and not because of 1D&D itself.
This is a case where the design will be determined by being incompatible enough to break with current 5e rules in a manner which isn't easy for an end-user to fix themselves with a few keyed in entries in a VTT by hand (or a simple unauthorized downloadable file). That's like designing a game with a lawyer over your shoulder.
My point: you are looking at this as a design decision and as a marketing decision, divorced from the real problems WotC faces in ensuring that current VTTs aren't compatible with the product because of their own forthcoming VTT. You want a 5,5e; they want a 5.5e. Notwithstanding that, I think it likely this is, in fact, a 6e in terms of actual compatibility.
The real 5.5e will be what Kobold Press (and perhaps others) publishes. Because unlike WotC - they WANT compatiblity with existing VTTS and will publish in a manner so that they are certain to get it.
And then it's 2009 and PF1 all over again.
