Why on earth would they do that? Why on earth would you abandon a winning focus?
The Switch is an unexpected runaway success; nay, rather, it's not just unexpected, it's defying virtually all industry projections and predictions. Splitting their focus to compete with the PS4P/XBX in a venue where they are vastly inferior and inexperienced just sounds retarded. I've thought about this quite a bit, and it seems apparent to me, finally, that the reason the Switch is succeeding precisely
because it is refusing to compete in that space. Sony and Microsoft have gone all-in on the eSport trend of the future. That's proven far more lucrative, but the Switch has proven a punchy underdog despite adopting the identical hardware strategy to the disastrous Wii U.
Why? The best answer is that it's because Sony and Microsoft have alienated and abandoned so many of the single-player experience gamer base. Thinking that Nintendo could be competitive in shooters misreads all the most cogent possible explanations for why the Switch has succeeded so wildly. The very first response from
@method115 hit it on the head: graphics/netcode aren't what Nintendo gamers want. The social dimension of the Switch lies in games like
1-2-Switch,
Mario Kart, or
Arms. It's couch co-op stuff and IRL social gaming; not virtual social gaming like on the PSN/XBL. Nintendo has no presence in that dimension.
In other words, Nintendo had a good idea, but they timed it poorly the first time around. They just needed to wait a little longer for the microtransactions and e-bro world of competitive online gaming to disenfranchise that many more among an old school world of gaming that is still obviously quite relevant; coupled with ten million moms dragging a bundle of munchkins hanging off their sleeves screaming about how the Wii is so old, they want the new one, and the moms not being able to fight them off by declaring they just bought the new console 2 years ago.
Finally, MS/Sony aren't picking up as many sales due to the tangential appeal of their own consoles as media centers; the market is saturated with households-- unlike in 2013-- that already have added some contemporary HTPC device (replacing their former system that tended to be a discrete Blu-Ray player) that handles all the streaming and apps of the world. Sprinkle in the fact that Sony decided the Vita wasn't profitable enough to pursue, while Google/Apple have made no real effort to compete outside an exclusive touchscreen format, and you get the perfect storm of niches coming together to form a powerful secondary market.
