UPDATE: We received a clarification from BlackBerry that they will NOT have native apps in the Amazon Appstore but rather it will only focus on bringing broader Android app access to regular BlackBerry 10 users. This means that BlackBerry World will focus on native BlackBerry 10 apps for enterprise along with consumer and enterprise productivity apps. BlackBerry 10 converted Android apps can still come to BlackBerry World but BlackBerry is going to recommend that they bring them over to the Amazon Appstore.
BlackBerry confirmed for me today that partnering with Amazon goes beyond bringing Amazon’s Android apps to BlackBerry 10. They confirmed that developers will be able to post native BlackBerry 10 Apps on BOTH Amazon and BlackBerry World. The focus for BlackBerry World will be Enterprise and productivity apps but even native BlackBerry developers will be able to take advantage of Amazon’s much superior appstore platform.
BlackBerry specifically told us that:
BlackBerry World is going to continue to be run by BlackBerry as our own storefront. We will focus on enterprise and productivity apps, while the Amazon Appstore will provide more of the consumer apps.
That means BlackBerry AND Amazon plan on helping developers (even native ones) to get their apps on both storefronts. I am still waiting to hear if the Amazon Appstore will be a native BlackBerry app though the Android port works just fine on my Z30.
