Default Wide AND fast con/pro-sumer zooms coming out?

Been keenly looking on the net at the new Nikon Coolpix 5400 soon to be released. What attracts me is the 28mm wide end of its 28-115mm equivalent zoom. Not many digital compacts around with that kind of scope. However, I've heard that the Coolpix 5000 which has nearly the same f2.8 lens has trouble focusing in low light. Whereas there are cams around with f2.0 zooms lenses (Canon G2,G3, Sony DSC-S85, Olympus C-5050) which are noted for their low light performance, but which don't go wider than equivalent 35mm without fussing about getting add-on lenses and adapters.
I know that wide-angles aren't typically super-fast, but does anyone know if such a cam is planned or on the horizon - with say a 28 - 115mm f2.0 lens for example? This would be right up my street. Any answers/ insights appreciated..

I tested the Coolpix 5000 versus the Minolta D7 (the original) last year and I remark that.
There are some Olympus with F 1.8 lens , but the zoom doesn’t go that wide.
How about the D7i with 28-200 without add on lens ?

Decided to go with the Dimage 7i over the 7Hi and CP5700 all because of price. Anyone looking for this camera, Gateway has them for $649 with 10% off (enter coupon code SAVE10), no sales tax and 2 day shipping.

Default 7i/7Hi

I find the Dimage 7i/7Hi too bulky. Also not an f2.0 lens. Looking for something smaller with faster lens, as well as the wide angle built in.

Why f2.0? What's the need...

Manufacturers can get away with using a smaller sensor hence changing the focal lenght equation and give you f1.8 with even a smaller lens (-> less $)! :lol:

... giving you even more DOF! If it's for more light then how many significant f-stop is that to an f2.8? :?

1 f-stop from f/2.8 t f/2.0 twice the light

And the smaller pixels on the smaller 1/1.8" CCD will capture only half of the light (ISO 50). So, where is the advantage?

Mark, i don't know. all i answered was the difference between f/2.8 and f/2.0 as NHL asked. i guess pixels might be equated to film grain. the smaller the grain the slower the film. on the pixel/grain, i'm not totally sure about that. the physics of the lens is the same for digital or film as far as light gathering. any of you experts want to chime in here?
