Not until I understand how backward compatibility will work and if there will be performance/resolution gains automatically, without the developer having to release an official patch. Also I would like to have an idea if there will be big differences in performance between PS5 and XSX for third party games.
1) most games
2) frame rate boosts possible.
3) resolution boosts possible.
We've known this fora few months already.
You only have to look at the PS4pro to know how BC is gonna work. It's the same thing but stronger.
