Unless the Windows RT tablets carve out a profitable niche reasonably quickly I think it is quite possible that developers (especially those targeting businesses) ignore it completely and continue to develop desktop apps.
A significant number will be converted. Many will not be. I didn't wait for the Surface Pro because it is heavier and the battery doesn't last as long, besides, my laptop still works great. And the while the Surface RT doesn't cover everything, it can do everything I want when I am on the road.
