>Stadia is a live platform that continuously improves.

Has Stadia improved since launch? The PS5 and Xbox Series X are both more powerful than Stadia instances, not to mention modern PCs. Has Google announced any timeframe for powering up their instances to match? Will I have to pay more to access instances with the power of next-generation consoles? Will those be available for all the games I purchased, or on a title-by-title basis?
