People talking about GTA6 being playable after launch is possible but I doubt it will impact their sales much as somebody will first have to rip this from the console then it has to work (I suspect the hardware requirements will make it harder to run than we think, limiting the mass appeal). Finally the money for blizzard is in the GTA Online its way more important for them long term than the single player campaign. And I do not see how AnyPS5 can help anyone there.

In general though bad news for all the small games out there more than the blockbusters.
