I also feel this way. Don't get me wrong...my 35 is a great lens and my most used by far. But I often would like it a bit wider.
It's funny that the big companies are so stuck in the mud in this regard while the little guys are thinking outside the box a little.
I'm not sure if any of Nikon's 50mm lenses are DX; I know Sony's 50/1.8 is APS-C only (the 50/1.4 is FF) and they have a 50/1.8 for the NEX system. Their normals are 35mm (as with Nikons DX 35/1.8).
Meanwhile, Samsung does a nice 30/2 pancake, Panasonic has the 20/1.7. Fuji did a 35mm normal, but opted for a 60mm macro/portrait lens instead of 50mm and will be doing a 27mm pancake lens. Sigma has 30mm; Tamron does 60mm (I know Nikon does, too).
It seems like these big, bureaucratic companies must just look at last years sales, see that 50mm lenses sell, and decide to stick with 50mm lenses (never mind that nobody really wants a 75mm equivalent) and so on. (Or in Canon's case, decided you don't need a dedicated 1.6X crop normal.)
But anyway, 28 versus 30 versus 35 isn't a make or break for me by any stretch; I'm perfectly happy with 35 (nice, light, sharp, fast, cheap) even if 28 feels like it has a little more breathing room.
