As Rol already covered, this is not Kotick saying "Switch 2 is on par with PS4/XBO" but rather "assuming it's closer to PS4/XBO [then the current Switch] then we can work with it."
Switch being close to PS4 in raw power wouldn't be a shocker given how far mobile tech has advanced since the Tegra X1 came out, but one should also remember that there has been a decade of technical advances since 2013, so just as the Switch has more modern graphical features than PS3/360/Wii U, the successor should have similar advantages over the PS4 and punch above its weight.
But for now, this is confirmation of nothing.
