Current version is 2.3 Gingerbread, which causes several issues.
BlackBerry has confirmed that BB 10 will eventually support apps for Google's Android Jelly Bean platform.
BlackBerry 10-powered devices have the ability to run Android applications through Android runtime. However, it's running on the old 2.3 Gingerbread version, which sees apps suffering lag and being generally unresponsive. BlackBerry now has announced that it'll update the runtime to Android 4.1 Jelly Bean.
The update will allow developers to easily port their Jelly Bean-based Android apps to BlackBerry 10. However, BlackBerry has yet to announce a launch time frame for the forthcoming upgrade.
BlackBerry, previously known as Research In Motion, said its newly-launched platform offers over 70,000 apps that include Android ports.

To me, thats still a lot. I have I think 4 apps I use on my phone... so when I see a selection of 1,000,000 or 70,000... its no difference to me.
It's sadly a marketing tactic to point this out while it really doesn't make much sense and yet works. Go ahead and debate a Apple fan-boy and he is bound to bring up the # of apps iOS has when literally 99.9% of them he will never use or likely even hear of.
