Yes, it will.
As for the performance on my end of things, its just unsatisfactory. Mind you, I'm the kind of guy to who will tests fighting games, but classic arcade-style games are just not an option for this kind of thing. I tried the Wi-fi, slideshow. Even with an Ethernet connection directly from my router while the thing was docked, it was a slideshow.
Honestly, to go on a soapbox about streaming for a second, while I get why solutions like the Steam Link and, from what I've experienced of Nvidia streaming are praised, the fact is, these solutions just aren't perfect, and its been done over and over again where this shit simply doesn't work with anything even resembling 100% connections with no distortion, lag, or whatever. The best experience I've ever personally had was using the Steam Link in my living room with six-eight walls between my main PC and my parents' TV. I was able to play through the first stage in Mega Man X and a little bit of Storm Eagle and experienced a surprisingly consistent connection, with some dropouts and lag here and there. But the whole appeal of the Switch is being able to take it with you, something that, given the current situation of how things are in the world, combined with the fact that the Switch is, IMO, not exactly one of those things you'd want to be caught by a robber at gunpoint with (don't you just love it when your state releases the violent prisoners due to a virus?), I just can't see the appeal of this idea when I have a TV connected to my PC where I can play everything in there when I have time and play something to pass the time the few times I go outside. Besides, I'd rather see native ports of the games people mention wanting to play on the Switch or emulation where possible.
But the fact is, the ceiling for emulation on the Switch is the same as that of the SHIELD TV's: Dreamcast, plus some GC and maybe Wii if you like to tinker around with shit. I am honestly tired of tinkering and would rather, at this point, focus more on playing games as opposed to making sure I can play KOF2002UM or KOF13 on my Switch when SNK are the ones leaving money on the table by not porting those versions of the games to the system as opposed to hacking together some emulator to run arcade games a WinXP machine in 2005 can play just fine, and, when you think about it, for less. I'd rather they port over the games that can't be emulated easily as opposed to WinKawaks/Raine/Nebula/NeoRAGEx/MAME 2003+-era games. That's something I'd pay for as opposed to the homebrew-esque original made by SNK on life support from EO-LITH!
