If you need more, they've expressed specific interest in doing a Planescape Torment Enhanced Edition after BG2:EE.
The good news about all these EEs is there's a very high chance any improvements made to the engine and UI of the future games will be rolled back in to the earlier releases as well.
They said they are also supporting cloud saves, possibly even PC/iPad syncing.
Last update, the platforms have not been exhausted... there's seemingly additional platforms besides PC/iPad to be announced.
hmm... wonder if thats hinting at android support then, can't think of what else it could be unless they went console.
