What makes you think so?
It's 7 years since the last tilt sensor equipped controller, surely there has been some advancements in the technology since then, not to speak of the fact that the PC's at that age weren't nearly as powerful as the PS3. Ineffective drivers coupled with PC's running with limited free resources must've introduced much of the lag then.
Most of the games then weren't after all designed for the tilt controllers, only a handful were and from what I remember the reports of those games were much more plositive than those that tried to use it as a replacement of a traditional controller.
And the PS3 controller isn't exactly a "gyro only" pad, it still has all the standard DS functions minus the rumble (which, while it was a nice feature in
some games, I think it's overemphasizing to say it was more than a gimmick after all).
The hands-on reports by the way have said the function is very responsive and there has not been reports of "delays" or unresponsiveness. i think it's wrong to apply assumptions from patchy implementations a decade ago to today.
The fact the controller is wireless gives it an advantage over the old Sidewinder controllers too.
The tilting certainly isn't suited to many game formats, for example I can't imagine playing a 3rd person adventure game with tilt function, it can bring a lot of variety in those games too. There could be sections, or minigames insidethose games that use the tilt sensor.
An example could be Oblivion, and it's "lock picking" minigame. With a tilt controller such minigame would be fun and more "immersive".
There's tons of similar examples where the tilt function could be used to
complement the analog sticks and buttons, not replace them.
At least the PS3 controller has
something new added, instead of being just a slightly redesigned last gen controller.
Funny, but I would've been completely satisfied with the "boomerang" controller with no added functionality over DS2, even without the rumble. But as the design is now the same old, I'm glad there is something new to it when I hold it in my hands a lot of my free time
And I'm still positive it'll be a worthy addition. Not as new and wholesome as the Wii's controller, but a nice enough addition nevertheless.
It's not something that sells the PS3 to new or hesitant customers, that true, and I don't think anyone in their right mind is arguing otherwise. A "gimmick" you could say, but that's what the consoles are, gimmicks, they're not necessities at all
