Now that I've looked it over, that survey is kind of weird.
First off, it's not THAT anticipated. Less than half of consumers and game shops are looking forward to it? The question wasn't whether they'd buy or stock it, just whether they were at all looking forward to it. You'd think that just having the name Playstation attached to it would at least get the vast majority interested in it.
The consumers and developers also aren't realistic about the features they want in it.
Sure, a hand-held that plays DVDs, goes online, acts as a phone, and has 3D graphics may sound great to these people when they take the survey but how many of them would actually still want to buy the thing if they found out how expensive it would be?
As for the developers. Many of them aren't even willing to develope 2D titles for the GBA despite its huge user-base, so I doubt they'd be clammoring to develope 3D titles for the PSP. As for online gaming, if the majority of developers aren't even willing to do it on the PS2, I don't see why they'd do it for the PSP.
All these things may sound good in theory but they wouldn't hold up in the reality of the market. Hopefully Sony will follow the advice of these survey-takers and kill any chance of the PSP being even a minor threat to the GBA's dominance
