Twitter tonight announced they have come to a agreement to acquire Atebits and it’s iPhone Twitter app called Tweetie. In the next few weeks, Tweetie will be rebranded as Twitter for iPhone and be made as a free app in the App Store for iPhone users.

For me, I have a hard time not believing that this acquisition is only just the beginning for Twitter in terms of developing and or owning their own official Twitter clients on multiple platforms. I predict that in the coming months, we’ll hear more about Twitter doing official clients for the PC, Mac, Android, Windows Phone 7, etc. Twitter previously announced Twitter for Blackberry. Will Twitter look to acquire someone like TweetDeck next?

So what does this mean for third party developers and their apps?

Will Twitter use their official client apps to take advantage of exclusive features they develop that no third party app can utilize?

It will be interesting to see what happens in this space in the next few months.
