Microsoft not allowing Java on future OS's is like pizza without cheese! I would put BIG money on Java sitting comfortably on all MS's future productions until the end of time!
Edit: Btw, does anybody know or have a link to any data on Java mobile distribution and downloads in 2012? With Android and iOS dominating the market especially in the last two quarters it's hard to find any statistics on whether java is worth still developing with in terms of mobile games...
