No - the question is whether *.msc apps will be rewritten to have a Metro-style UI, not whether the legacy Win32-UI can be launched from the Metro start screen.
This leads onto the general point of how much of "old" Windows will become Metro-style. Will we also get Metro-Word, Metro-Excel as well ? If not, we are going to have a very schizophrenic Windows experience, continually switching between the two UI
styles!
