Gotcha.I wouldn't read into it too much. All I said was 'getting their games running' whether that would take the form of backward compatible patches or new purchases, I don't have any idea.
The only thing I was trying to say was that whether it's Scarlet or the PS5, third parties aren't that invested in development for those platforms, at this stage. In that sense, it doesn't matter all that much if Microsoft deliver their dev kits a little late.
