Windows RT literally came out six months ago, Windows 8 is barely coming on the radar's of developers. Even with Windows Phone 8, all of a sudden, app developers are going on Windows Phone. A major app model change and a major UI change and a major OS change like that doesn't get adopted in six days.

For how long was Windows 8 available as previews etc? Six days? Microsoft is well known to engage developers very early before final release of a product, to ensure that things roll on quickly and smoothly from the outset. What happened? Lack of interest?
The entire premise of Windows 8 is the MPI, a complete cross-platform OS. Developers can't abandon Windows 8 for Windows Phone, because they are one and the same. Aren't they? And we aren't really talking about the MPI here, were talking about what it can provide. Which, at the moment, is very little.
