It is true. Where are the majority of 3rd party games? No Far Cry 5? Where are the games? Down graded ports of a handful of games don't really count for much.
Fact that Switch not receiving some games doesn't mean that those games can be ported to Switch or that Switch cant run them.
You shouldn't be counting chickens before they hatch. We don't know what kind of legs the ns will have. It could turn out to ha ve better legs than the ps2 or it could fizzle out quicker than expected. Sony doesn't need to risk any resources on something that's still experimental and might not work for them (if sony tried it) when they could use those resources on ps4 games and ps5 dev/games.
