I don't think Switch 2 can launch the same year as PS6, but I can see a scenario where Switch 2 launches 1-2 years before PS6. That would clearly put those systems in the same generation whereas now the Switch launched 3.5 years before the PS5, so people are unclear how to classify it. So if Switch 2 launches in 2025 and PS6 launches in 2026-2027, then the time frames of the two systems would be closer in synch. But I don't think Switch 2 will launch in 2027, for example. That seems far too late for a possible launch to me.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
