Is NBA 2K21 for Stadia gonna look like the one for PS5?
@StadiaTeam -- when will be be able to pre-order 2k21 in order to get bonus content?
NBA 2K21 is out now on Stadia .
Based on this graphic taken from the NBA subreddit. We're not getting the next gen version. I'm assuming that means we're get graphics equivalent to the PS4 graphics, yes. This is pure speculation though.

Will it upgrade on Next Gen once Stadia will put upscaled servers to 8K.
Sunny posted a YouTube video on NBA 2k21 running on Stadia.
It is the current version and NOT the next gen version. A pass for me... It looks almost the same as 2k20.
