You can download the new Skype right now
If anyone gives a damn about the Skype app, 9to5Mac reports that the app is being pulled ahead of the 5.0 update. But in fact, if you delete the app now and go to the Purchases tab, it will be version 5.0 when you download it.
Yeah, ignore those other purchases.
If you can't wait for the update, try it out. It might take a while to find the Skype app though, if it was purchased a really long time ago.
