Wholly to be expected at this point. Until Windows 8 hits the shelves and people start using it there is little incentive to build specifically for it - and since Win7 apps run perfectly well in Win8 there is little reason to focus on Windows 8 by itself at this point.

Once the WinRT tablets get into peoples hands the call for RT-specific apps will increase.

Plus, the WinRT dev environment really isn't as fully baked as we've grown accustomed to in the Windows world. So many things just simply don't exist at this point. I've been looking at building a Javascript-based WinRT project - one of the suggested app build paths suggested by MS and discovered that there is no touch-and-drag support built in yet. You can roll your own using JS-events but .... really, things like that dampen the enthusiasm.
