How will it unfold?
PERSONAL LEVEL-- I think it will unfold in a way that doesn't make me a customer. They are pretty much there. I love the rules-set, I even bought the core books recently just cos I do. But it's far easier and less time consuming for me to go over to Paizo.com or DTRPG and buy a PDF, or grab a cheap used D20 Kalamar/Necro/Goodman book off Amazon, and run it with those rules, instead of converting it to 5E, making my own, or converting and running yet again some old module in my collection I have done 20 times since in nearly twice as many years. I'd rather do the work , but its not feasible with the nature of my job, 2 kids, their hobbies/afterschool/school activities, my wife and her job schedule, and a home to keep in order. Carving out 4-5 hours of session time every other weekend is tough enough.
With so many OGL/SRD games out there providing a wide variety of support products (PF, C&C, DCC, 13A, DW, OSR, etc), I would rather support those designers/companies, instead of WOTC (which sucks, cos I really want to support folks like Mearls, Perkins, Greenwood, Rodney-prior to his resignation, etc).
BUSINESS LEVEL-This assumes no effective 3rd party license ala the SRD/OGL-My feeling is that there will be a big shift at some point due to lack of traditional support and current TTRPG model- either there will be a flurry of product to invigorate a bored/product starved fanbase, or the opposite, the TT game will be on life support with less TT product, and the budget gets slashed further to work with licensing, novels, and electronic products. Swing that Branding Iron.
That said, it's not a big deal in the grand scheme of things to me- I'd hate to see D&D the game, or The Brand go the way of the do-do, but I wouldn't lose any sleep over it. I got upset when TSR died, but I don't have that same warm and fuzzy feeling about WOTC like I did with TSR during the golden age.
Thats my 2 clacks.
