Remember last year we reported that RIM would be holding a Blackberry 10 app port-a-thon over the weekend? Well that weekend has since come and gone, but in the meantime it looks like the event might have been a success as it seems that a whopping 15,000 Blackberry 10 apps were submitted in the process! Granted there is a chance that not all of them will be making it into the store, but it also means that RIM will have a wide selection of apps to choose from to load up into their stores once Blackberry 10 has gone live. We expect that the incentives such as $100 per approved app, free Playbooks and a chance to win a Blackberry 10 Dev Alpha device probably helped sweeten the deal, and based on our calculations, assuming all apps make the cut, RIM will be paying out $1.5 million to the developers involved! Not too shabby! Now we know that RIM promised to have at least 70,000 apps available for Blackberry 10 devices at launch and with these 15,000 submitted apps, we wouldn’t be surprised if RIM will be able to meet their goal.
