Angry Birds maker Rovio may be looking to the indie market to expand its game portfolio. “We have some plans for this area, but not ready to announce yet. If we do something in the publishing area, you can expect it to be a bit different,” says Rovio executive Peter Vesterbacka. And different could be quite good for the team behind Angry Birds, an Android game that’s reached cult status. Many wonder how long Rovio will be able to ride the Angry Birds wave, so the developer’s next move will be a highly anticipated one.
