According to BlackBerry Leaks, a reliable source in the past, BlackBerry is already working hard to bring BBM on Windows Phone 8 platform. In addition, the cited source also claims that BlackBerry Messenger will arrive on iPads and Android tablets.
Desktop and web versions of BBM are also in plan, which seems extremely plausible given the fact that BlackBerry officials demoed a desktop version of a BBM only a few weeks ago.
