Maybe. I actually expect that IF Wizards plans for a VTT come to fruition (a very big if IMHO) then the game will change even more slowly over time than it is now. Because making even minor changes to large scale software projects is a lot harder than tweaking rules in a text format. And the rules that do change will be as you say ones to make it slightly more easy for the VTT folks to implement in code, rather than ones that impact the play experience at the table.Indeed. Whether things will stay this way is more of an open question. I'd be extremely unsurprised if 1D&D gradually accumulated minor changes to default methods to suit VTT play better.
