This reads like:
- we are struggling to get good battery life on this thing, but still trying,
- not worth being backwards compatible to Wii U, because a lot of these games will be repurposed for Switch to provide a good launch library
- not worth being backwards compatible to 3DS, because that will still be in the market for at least a year (or it might not be a touchscreen)
- we are still working on the system UI, which might be android, so we are not confident to talk about the presence of mobile games yet (or it might not be touchscreen)
The whole thing is screaming struggles in production unfortunately. I hope they pull it off, because the concept could be brilliant.
