That's basically my point too right now, unless the PS4K and XB1.5 talk is upsetting old PS4/XB1 fans enough to want to jump ship I don't see power being enough of a big deal to steal back some users from the PS/Xbox ecosystem. They're stuck, they still want to play Halo, Uncharted, Forza, Gran Turismo, Gears of War, God of War etc.
It's better to try to get that unique secondary console spot where they're not competing directly with any of the other two but still get those gamers to want the new Nintendo console next to their other core gaming machine of choice, be that PC, PS4/4K or XB1/1.5.
I honestly don't think Nintendo will get any wows and crazy cheering this year by slightly beating PS4 and XB1 in power, even if they're also beating their rumored upgrades. They need to do their usual thing and evolve gaming in some way so even PC gamers simply can't play that way on their $3000 gaming rigs either. VR is a big of enough deal right now that anything ordinary no matter how powerful it is will get the "meh" respons from the masses.
