Well, this is a drag. Citing contractual issues, the people who made Baldur's Gate: Enhanced Edition have removed it from sale on their site and the Apple App store. The game won't be getting an upcoming patch, and the Android version has been put on hold, as has the planned enhanced edition of Baldur's Gate II.
Don't worry, though: if you've already downloaded the game, it won't just up and disappear. You'll be able to keep your copy. Beamdog, the Extended Edition's maker, says, "If you have already purchased Baldur's Gate: Enhanced Edition from Beamdog or the Apple App Store, you can still download and play your game."
Beamdog president Trent Oster addressed the issue in a letter posted to the BG:EE website:
Dear Friends of Baldur's Gate,
We recently removed Baldur's Gate: Enhanced Edition from sale on Beamdog and the Apple App Store. We've taken this step at our publishing partner's request as we attempt to resolve a number of contractual issues.
Unfortunately, until this matter is resolved, we are unable to release the latest Baldur's Gate: Enhanced Edition patch or Baldur's Gate: Enhanced Edition for Android.
This also prevents the launch of Baldur's Gate II: Enhanced Edition. I sincerely apologise to the series' fans and promise we are working diligently to remedy the situation.
President, Beamdog & Overhaul Games
There's a FAQ posted to the Baldur's Gate site in which Beamdog says they're unable to discuss the "complex legal matters" surrounding what's going on. As for Baldur's Gate II: EE, they've got this to say:
We have been developing Baldur's Gate II: Enhanced Edition for some time now, but until all issues with our publishing partner are resolved we cannot officially announce or offer this game for sale. This has resulted in significant amounts of wailing and gnashing of teeth amongst the development team.
Such a bummer. We've reached out to Beamdog and will update if and when we learn more.
