For me, this gets back to where it was before this whole kerfuffle: how different is the next edition going to be? What's happened has made a significant impact on the game, though, as many companies who's product I like were starting to design their own systems that are 5E compatible. Will that actually still happen?
The reason I ask that is because if 6E is more of a 5.5/5.25E, where there are minor changes, but you can still use 5E books/classes/spells I can just pick one of the many 5E clones and use that. What's more, I can use it on Foundry or Roll20 and just ignore what WotC is doing entirely. Maybe I'll pick up an expansion book here or there if it interests me, but unless WotC changes their publishing model, how many would that actually be? There will have to be something really interesting in 6E in terms of rules to make me adopt it.
The funny thing was, before this all happened, I expected I would pick up the 6E PHB just to be up to date, and if my group was going to use the VTT, I'd get a sub to that as well. Now, unless there's something really new and different (which WotC has said isn't the plan) I can just use whatever 5E product that launches from a third part company.
I think this is the textbook definition of a pyrrhic victory at this point.
