BlackBerry 10 Platform Choice
BlackBerry 10 is an open platform that provides a variety of development languages and runtimes designed to fit your skills. Your choice will be based on a combination of familiarity, possibly having a pre-existing codebase as well as the target devices you wish to serve.
The BlackBerry NDK supports many open standards to allow you to bring your existing app to the platform. The dedicated resources provided means your app is as close to the hardware as possible.
Cascades has been designed to allow you to easily build a BlackBerry native application using an entire framework integrated with core services which provide an astonishing user experience.
If you have an existing game or app written in AIR that you are looking to bring to the PlayBook and future BB10 platform this is the choice for you.
