RIM is set to launch a dedicated enterprise app store for its PlayBook tablet device, although the timeframe for availability was not revealed.

In the company’s earnings conference call last week, Mike Lazaridis, its co-CEO, also said that the release of the Native SDK for its recently renamed BlackBerry 10 platform makes the development of games for PlayBook “an extremely attractive proposition for developers.” He said that approximately 100 native games had been submitted to App World, from publishers including EA and Gameloft.

RIM has previously said that the lack of a strong supporting ecosystem has hampered its PlayBook device. The company noted that apps developed now using the Native SDK will also be supported by future BlackBerry 10 smartphones – although these are not set to reach the market until the second half of 2012.

According to the executive, there are now more than 50,000 apps available from App World across RIM’s various platforms, with 5 million app downloads every day. It was also noted that there are 380 BBM Connected apps available in App World, which represent almost 20 percent of the daily downloads.
