Angry Birds on Windows Phone has less content than others, no timeline for updates

When we reviewed Angry Birds for Windows Phone, we noticed that the port was based on an earlier version (specifically v1.4.2). We figured this would lead to less content in the game and so we decided to try to plow through the game as quickly as possible to see when we'd hit our limit. Turns out it's fairly soon as we discovered chapters 10 and above are locked (you are greeted with the above photo once you reach that point). That also means it is missing two worlds: "Ham 'em High" and "Mine and Dine". Quick calculations of numbers give us the total of 135 levels for the Windows Phone port.

Now compare that to the latest version of Angry Birds on iOS and Android, both of which are now on version 1.6.1. How many levels do those ports have? Both top out at chapter 17 level 15 which, assuming each chapter consists of 15 each, means that iOS and Android have 105 more levels than the Windows Phone port. What's worse is that the Windows Phone port is also more expensive at $2.99, compared to $0.99 on iOS and free on Android. Even the WebOS port which is also on an older version (1.5.3) has 60 more levels than Windows Phone and it is still cheaper at $1.99.

We contacted both Rovio Mobile, the original creators of the game, as well as Innogiant Ltd. which assisted in the development of the Windows Phone version. A representative from Innogiant responded, but kindly told us to ask Rovio instead. Rovio has not responded at the time of this writing, so we really have no idea when these content updates could be pushed out.

How do you feel about Windows Phone getting the shaft with Angry Birds? Does it set the wrong precedent for future Xbox Live games or have you already spotted others guilty of the crime?

Update: Earlier today we received a response from Rovio. Here's their (non)comment on the matter:

Thank you for contacting Rovio Mobile and for your interest in Angry Birds. Unfortunately, our company policy is not to give out any information regarding updates or release dates. This is to make sure we can finalize the updates without external time pressure and because we do not want to give out release dates that we cannot guarantee we will make.

So sit tight folks, we could be waiting a while.
