Id Software's John Carmack has said he thinks the PlayStation Vita tech will feel "pretty pokey" a year or two after launch.
Speaking to Gamespot at E3, Carmack said the Vita is twice as powerful as a smartphone with the same chips inside, simply due to the way Sony is directing people to program for the device.
However, the id think tank seems sceptical that the Sony portable can keep up with the pace of technology in the smartphone market.When asked whether he'd had chance to look at the PlayStation Vita first hand, Carmack responded:
"No, but I think that Sony learned a lot from the PS3, and they've gone out of their way to make sure that the development is as easy as possible on there. However, I wouldn't want to be the executive making the decision to launch a new portable gaming machine in the post-smartphone world.
"I think that they've picked as eminently a suitable hardware spec as they could for that. They're going to have you program for it like a console, so it's going to seem twice as powerful as a smartphone with the exact same chips in there," he told Gamespot
"But of course, by the time they actually ship, there may be smartphones or these tablets with twice as much power as what they're shipping with on there. And a year or two after that, it's going to look pretty pokey."
Carmack suggests that Sony's success will come from focusing on quicker and cheaper games for the Vita.
"The key to their success, if there's going to be a success there, is allowing people to more or less directly move over the console development engine to technologies on there. Because you know, you don't have people making $50 million budget iOS games.
"You make a game that's fun and quick to do, and you grab low-hanging fruit with the technology there. So, even if that plays out, such that people find that they can easily bring over their full-on, full-blown AAA console titles and put it on [the Vita], that's going to give it a reason for existence."
Impressions from E3 on the new handheld, however, have been very positive. Our man in L.A Tim Clark got his hands all over one and was very impressed. Watch his Vita hands-on video to find out why.
