You laugh but there was someone yesterday thinking the Switch was about as powerful as the Vita.
On GAF at least, possibly elsewhere, the Switch is seen as massively underpowered. It'll probably be like this until the system gets released and we start seeing third party ports in the wild.
Trust me, I'm not laughing over here, I responded to that post yesterday. Even on purely a flops scale the Switch is over 10x stronger than the Vita, and far stronger in real world performance.
I think a lot of people have a fundamental misunderstanding of processing power, and in general how games are made. The only thing which could possibly prevent a game from working
whatsoever on the Switch is a very poor CPU, but everything we have now points to the CPU being the stronger component, and very possibly stronger than those in the PS4/XB1. So any game should be technically feasible on the Switch.
Of course that doesn't mean we should expect ports of every (or even many) games, as the cost of developing ports likely wouldn't outweigh the returns at this point. But I will guarantee right now that if the Switch takes off like the Wii did you will see a lot of ports, as it is much more comparable to PS4/XB1 than the Wii was to PS3/360.
You mean third party ports from PS4 and One? There are any announced?
So far Steep is the only one which is purely a PS4/XB1 port I believe. It's rumored to be getting the new Assassin's Creed this year, but I think Steep is the only one officially announced yet. E3 should be interesting.
