If you are willing to wait for the games, then I'd suggest just waiting for the hardware as well. The games might come to Switch, or they might not and you buy a cheaper X|S. If you are wanting to play games right now, then get a cheap PC. There are more gaming options there.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
