Longing for an updated version of Tweetie for Mac? Well, come tomorrow — rumored to be exactly at noon ET when the Mac App Store launches — Tweetie for Mac will be rebranded as Twitter for Mac and immediately available. The screenshot up top was dug up by Razorianfly, and the new Twitter application should bring native retweeting, real-time updates, and “drag and drop” tweets — though we have no idea what that last one is. Hit us up on Twitter — @BGR — when the App Store launches and you’ve downloaded the new Twitter for Mac hotness, alright?
