Possible New Features To Be Added?

Hey everybody. So recently, I've been looking through my phone's files. Some of them being the ABT folders. Inside them, I saw some interesting things:This is a picture of the Characters folder. Here you can see a 5MB file for the Transformer Drift, and another file for Superion: https://www.angrybirdsnest.com/members/partshade/album/picture/15744/This is another picture of the Characters folder but scrolled down. You can see a file for the well known charater Megapork: https://www.angrybirdsnest.com/members/partshade/album/picture/15745/And finally this is the data folder for the nodes. You know about Cobalt, Pig City, Desert and Meadow (The Forest). But what about Tunnel? https://www.angrybirdsnest.com/members/partshade/album/picture/15746/Could these possibly be new features to be added to the game soon?
