Nintendo has said Switch successor before. So, unless they're being weird and planning to launch a Switch Pro in 2025, and then Switch 2 in 2027-2028, it's not a Pro. And even then, what would Nintendo gain from a Pro coming out 8 years later and with the generational leap in graphics that are saved for a successor?
99% chance the new hardware is Switch 2, not Switch Pro.
