Is it really a change that you’re suggesting? More games aren’t a change, that’s what is planned (literally more games announced in the future). Adding games to PS+? Happened with the first, so not a change there either, just continuation. Update games from PSVR to PSVR2, not a change since PSVR didn’t have a back catalog of games.
I definitely think they need to pump out the games to outsell PSVR, but that’s not a change to what they’ve been doing. The rest I’m not sure will truly push sales that much. A price reduction of at least $100 will push sales way more than any of that in the first year, though.
