I dont think itll be high powered, thats just the reporter adding something for clickbait.
Im one to believe in Bobby Kottick mentioning that the Switch 2 is roughly the power of a PS4 as he was in contempt of the court when his leak of its performance was discussed. the handheld likely has better cpu performance though vs ps4, as its basically in the same playing field as the steam deck is, both companies who can sit and make thir 30% cut from developer games.
Tldr, dont expect Series S perf, expect steam deck performance with better battery and DLSS support to 4k (i personally believe itll target 1080p60, and use DLSS Performamce preset to upscale to 4k, as 1440p tvs arent common)
