There's some things that may come out... Sonic Dash will be free, will have all of the features that the iOS version currently has (and sadly Android Users, you're going to have to get Shadow and Blaze all by yourselves, and I don't know about that Zazz Boss, yet), plus that will Also include Google Play Games Services. If you don't know it, it's really similar to Game Center but it' smade from Google, uses G+ intergration, it's Cross Platform (so If you use it on an Android device, I can also use it on an iOS Device, too), plus it has cloud save, so you don't have to start with 0 Points or something. I know that many games are really starting to have such feature, but the just recently, Play Games Services included was Sonic & All Stars Racing on Android Devices, and it's the First Sonic Game to have that included. All of this was from Hardlight which I really talk with them about some all of this that I said that will be important as the Android Version gets closer to Google Play.
