If the Chairman did prematurely announce a full-frame "M9" then it's no wonder he's been hung out to dry.
Leica has had a lot of start-up problems with the M8 (IR problems and overall realiability etc.) but has sold a fair number to it's die-hard consumers. To indicate that these folk, having already purchased a somewhat "dodgy" camera are now going to be abandoned is quite a PR faux pas.
However, I suspect too, that the M8 is just not selling well (the "problems" don't help) and they aren't recouping the R&D costs, much less turning a profit with it.
