No, a console being successful only based on the merit of specs has never been true since the first generation. What really matters is the games. One thing that Nintendo has obviously learned with the DS+Wii is that new gaming experiences trumps the specs race. What they've also learned with the Wii U is that those new experiences are totally supported by software. If Nintendo really, and I mean really succeeds to sell the concept of the Switch to the market mainly though games, mobiles phones and home console will feel outdated almost overnight.
I'm not saying the Switch won't be successful. I'm saying R* isn't bringing RDR2 to Switch because not enough people ask for it.
And the bolded it just, come on. I don't know what exactly you mean with "outdated", but games on smart phones have taken a spot in people's lives that dedicated video game hardware will never reach.
