Do you really think Microsoft wouldn't prefer that in the future they make it so most people choose the Windows store over anything else, by pushing it even more into their faces, like they did with Metro?
Many people asked for the Start Menu to be back in the desktop mode, and they didn't bring it back? Why would they do that, when it doesn't interfere at all with Metro mode to just have that in the desktop mode? Why else would they do that, if they didn't want to force Metro even more on you by turning it into a shortcut to Metro mode instead?
