Actually as far as we know, it probably will.
"I think that the ability to do things that other devices can do will be a reason to make sure you own a Vita, and maybe why you leave the other devices at home," Tretton said.
"I’ve certainly gotten that way, I don’t carry a laptop anymore. Something like a Blackberry’s perfect for the vast majority of what I need a laptop for. And then I think when it comes to entertainment, you’ll find that Vita will do everything, and maybe do things better, than any other device that you’re using."
Other devices are flash enabled and can play videos online. The Xperia play has a good browser and flash, so does many smartphones and tablets. If we want to leave the other devices at home, then the psvita should be able to browse the internet and go on youtube just like all of our other devices.
boy oh boy they had better because i will be extremely disappointing. It makes no sense either. so what if i am on The playstation website and i wish to watch a clip, i have to go grab my laptop??? thats very narcissistic on their part in my eyes. people waiting a very long and loyal time so i sincerely hope that i can do something as simple as watching a two minute youtube video. I trust that it will be available very soon.
