In fairness the 3DS was announced in 2010, the PS3 in 2005 (?) ... if the DS and PS2 could leg out to 150+ million, then if your whole argument is Switch is actually a better seller than those two ... well it was also some weak shit to say "yeah but we can't have Switch 2 announced or talked about until like 8 years into the product cycle!".
Switch has already had a pretty large advantage in being 7 years old and still not having an official announcement of a successor even though we know now dev kits are out in the wild and that news is spreading.
If you need a product cycle where you have like 8 years all to yourself and no successor announcement ... I mean, it kind of diminishes the idea that you're actually the best seller, it's more that you just have the more favorable circumstances (ridiculously favorable frankly).
