Speaking to Kinda Funny, [Oddworld creator Lorne] Lanning states that he has "no faith," in the Switch, due to "experience," and having seen how the Wii and Wii U played out. To clarify the condemnation of the former he explains that both consoles weren't successful for third parties, and that Nintendo ended up making all the money at the end of their runs. He experienced this with what he claims is lackluster promotion for New 'n' Tasty on the Wii U.
While praises that it's mobile he doesn't think people are going to go through the effort to work on an "under-powered console" (a sentiment THQ Nordic shares), and that in conjunction with their alleged efforts to ignore third parties to better themselves, it'll end up hurting studios.
It's something a lot of developers are struggling with right now -- whether or not to call out Nintendo after the Wii U situation. The Switch is doing great so you don't want to burn that bridge, but some studios have claimed that even after they've tried to make games for it Nintendo hasn't reciprocated. If more developers aren't willing to speak out like this and share their opinions we'll continue to be in the dark.Nintendo alone simply weren't able to release enough games to save the WiiU, so the general consensus is that Nintendo's Switch will either live or die depending on the amount of support it receives from third party developers. The fact that previously-burned developers are hesitant to invest heavily in developing for the new platform is basically the opposite of what Nintendo need to happen, in order for the Switch to succeed where the WiiU failed.
It doesn't help that the Switch is simply underpowered compared to competing consoles, either. In a world where the Nintendo's competition consists of Sony's PS4 Pro, Microsoft's XBO-X, and even more powerful gaming PCs, the Switch can't even keep pace with a vanilla PS4 or XBox One. Most of the Switch's 3rd-party games are ports of old PC titles, but even that well could run try quickly as developers continue to wrestle with the limitations of the Switch's underpowered hardware.
The Switch managed a decent launch, but Nintendo still have a lot of problems still to overcome in order for their new device into have the kind of legs that they desperately need it to.
