A game can be 720 native on Vita. Without upressing. Because most games don't is irrelevant. Most high profile 360 games were sub 720.

...No it can't. The Vita doesn't have a 720p screen. It's impossible.

I agree with this sentiment generally, though I definitely don't think it will last 10 years. 8 years max. 6 years minimum, though, for the same reasons you say.

Although the screen wasnt 720. It's max output was always that.

Don't forget it was originally expected to have HDMI output built into it.

It doesn't, though. No game has been made to run at native 720p, and any that tried and somehow streamed to a TV or something would look absolutely awful because the only reason the best looking Vita games can even look comparable to PS360 games is because their resolution doesn't need to surpass 544p, meaning more resources can go to polygon count and texture quality.

Whenever it slows in Japan. That region is still selling them at a decent rate.

As a sony platform with a growing strength in Japan, I feel it'll last a couple years, at least 5 and perhaps up to 8 or 10 years. Elsewhere, it will probably continue doing well enough, at least in Europe. Not sure if anything can help it in the US.

It's almost dead in the US. Europe will keep buying it for a few years as long as the strong Japanese support continues.

Japan at a minimum 2018 but I can honestly see it going even longer. They already have great Japanese support but if the NX handheld is similar in power the vita might actually start getting more games.

Either way the answer is, when the Japanese stop buying it which will be a long time.

This year in the west. Next year in Japan
Maybe early 2017 in the west and early 2018 in japan

OP: I think it will be discontinued only in 2019.
