"Standard" and "Improvise" are two polar opposites. You can have a fancy new car without having to redesign the wheel!
In any case, Blu-Ray is an evolutionary step, the Eyetoy was a gimmick at best (And, arguably, even though the tech is mature enough to be useful these days, still is), and the Cell processor is too much of a background detail. Nobody but tech-addicts like ourselves would care about it if it wasn't a part of their marketing - it's a fancy processor design, but it's not magic, and I would say a failed experiment. It would not surprise me in the least if the PS4 went back to a more traditional setup, with several general purpose units, rather than the cell's one general purpose unit and 6 special purpose units, as developers haven't shown any particular interest in taking advantage of that. Far from being the element that puts the PS3 ahead of the pack, most of its problems come from it. The design has its uses (And it's certainly not a new concept, not by a long way), but apparently gaming is not one of them.
(And for the record, '64-bit games' is a marketing term, referring to the bus size of the GPU - a 128bit bus lets you push more data. The 360's Xenon is a 64bit chip, I believe, so funnily enough we *are* still playing 64bit games - but again, that's a purely background technical issue, and has no bearing on anyone. To market a console based on CPU architecture or bus size are just more modern equivalents of blast processing)
i agree the eye toy was a gimmick, but that gimmick led to a motion gaming craze that is begining to flood the market. i agree sony probly wont use an upgraded version of the cell in the ps4. but whos to say that a computer company isnt improving on its design right now. you never know man, all processors in the near future may end up using its desing. i seriosly doubt that the 360 still uses a 64 bit gpu.
