Angry Birds Rio, the next installment in the Angry Birds saga, is set for a March release, and it's a tie-in to animated feature Rio. Cross promotion FTW! Rio will include 45 new, Rio-themed levels, with Rio-environments, Rio pigs, Rio birds. Rio, Rio, Rio! You should be very aware of animated film Rio!
This screenshot could well be from Angry Birds Rio, but who knows at this point? It will all become clear in the near future, I imagine.
Whether the game will be free or whether gamers will be expected to pay to watch a game commercial (gamercial?) remains to be seen. I hope for the former, but expect the latter.
Angry Birds is unarguably a fun game, but now that every human on earth is playing (or at least aware of it), how long until it "jumps the shark" and goes from fun, little time-waster to "OMG! Please stop talking about Angry Birds!?"
