Of course,
There’s always an alternative…
Steam Deck
A handheld gaming PC, with decent stats, and numerous options.
Steam drops a video, and in that video is a ‘hint.’ — NMS Mobile!
I do see the appeal, Sean. Stronger and more versatile than Switch.
Cellular Service > Smartphone > Hotspot (or Tether) > Steam Deck > W-Fi (or Port)
Should even run Stadia, PlayStation Now, GeForce Now, and Xbox xCloud (cloud gaming). 
Granted, why even pursue ‘cloud gaming’ when you got Steam? (Because ‘cloud gaming’ puts you on a smartphone. One device.) Does this mean Nintendo may finally beef-up a stronger alternative? 
It would be nice to get on the Nintendo platform, reaching that audience, as well. But, such is of course very optional and there’s always… maybe… Nintendo next gen?
Nonetheless, one device would certainly seem simpler, and cheaper…
Smartphone > Cloud Gaming -OR- Steam Deck with built-in Cellular Service (hint)
- Which option(s) will prove best? One, some or embrace them all?
- Would getting on all platforms overwhelm Hello Games? (Think)
After all, everyone already owns a smartphone. One device for everything!
Of course, with Steam Deck offering a portable product similar to a gaming laptop, comes the ability to experience corded (or ‘wired’) internet, and therefore without any of the mild latency of ‘cloud gaming.’
Good mercy, getting interesting!
QUESTION:
Can this thing handle VR headsets? 
Consider this article…
Notice above…
“connect with any hardware”
Consider…
We’ve seen the Nintendo Switch turned into a cardboard-based VR headset (Labo VR or ‘Toy-Con’). So, if the Switch can handle still very playable a version of VR, then the Steam Deck can easily. (Think about it)
CONCEPT:
Connectivity for a Labo VR crossover? Design a cardboard template? - and/or etc.
Now consider next gen - Gonna be lit!
