If you have been following the other thread about this, you probably would know that its not coming, and there is no news from Rovio as of now.
I mean, personally, i'm not surprised. iOS and Android are in fact the 2 leading platform, with the most amount of resources. BlackBerry's QNX platform is still lacking behind in user base, with only one device out in the market now. So, it makes sense that Rovio would dedicate most of their resources for that first. Until, BB10 hits, and more devices are using it, the blackberry platform will always be at the bottom of the priority list. I'm not saying i agree with them doing that, but i'm just saying its understandable. I have no doubt that it will eventually arrive on playbook, since they already have most of their other series of angry birds out for playbook. And i'm sure they made a good chunk of money out of us. So its only logical they would continue with it.
Be patient my friend, unfortunately now we just have to be patient.
