Pascal with 16nm should have no problem with 1080p with pretty great graphics. X1 was already far faster than xbox360/ps3. I'm guessing GDDR5x or something also, or at least something faster than what is now in xbox1/ps4. The idea this chip is expensive is just silly. The HUGE chips in xbox1/ps4 are $100 and $115 with AMD making about 10-15% on them. That is not cheap. Socs however, from NV and everyone else are $25-40. T4 went for $25-30 as shown in xiaomi docs with actual build costs. Even they only paid $28 and they are much smaller than MS/Google who reportedly paid $20-25 for the previous versions. Knowing the power drop with pascal over the already impressive maxwell, this should have some decent battery life.
What may make it interesting to many users, is if they include streaming from NV gpus. Don't forget NV owns 75-80% of the market here. They would lose me as a potential buyer without that. If I can't stream my PC gpu to it, I'll wait for NV's update to shield tv which should be awesome with GDDR5x and hopefully they'll aim it at 100+watts this time! I'm in if they aim for xbox1/ps4 wattage. Shield TV is already impressive, but I want 100w and dual chips like xbox1/ps4 (or at least far larger custom gpu side), for a serious android vulkan box. Streaming my next gpu to it is icing on the cake, which unless Vega is awesome, will likely be NV top end. I'd have no problem with $300-350 if NV did this but would not pay that for another 25w box (go big or go home). 2x 16nm pascal socs+SSD+GDDR5x+gpu streaming and a slot for a 2nd HD would be sweet.
I'd also like to see android games work on Nintendo's box, or again, probably a pass for me. Since it has tegra, not sure why they can't adapt it for android/vulkan etc. Android has a pretty massive library of great games I already want to play and growing longer all the time. Because mobile has had limited power, the are a lot of games where they really concentrated on the FUN part. That part is missing in many PC games these days that just seem to throw graphics at the game but forget to make it fun also. If it's fun people buy it, period. If the games are $30 rather than current consoles $60 they'll also sell well, and to a much larger audience. I don't know many people that have more than a dozen xbox360/ps4 games (myself included) if they also have a PC.
Nintendo DS sold 155mil units. That is more than double PS4/Xbox1 combined. Your game can be $30 bucks and still make a killing. With xbox1/ps4 you have to make two versions of your game to get less than 1/2 the audience of a DS. If this thing sells 100mil+, or even the 60mil of 3DS (again, equaling combined ps4/xbox1 sales), devs will pretty much flock to it. This is much more capable than 3ds/vita (portable and great vid streamer, tv console etc this time), so I'd expect sales to beat those combined (about 73mil) over it's life, since it appeals to both tv people and mobile. Of course if it's price is $350, nobody will bite...LOL. I'm guessing $250 or less though with xbox1 S being $299 and more powerful. Though the multi-purpose stuff might be worth $300 to some I guess but at that price it had better stream PC gpus too. NV would be silly to not allow that if they want tegra to really take off finally (aside from cars that is).
