@Madrict Yes, there will be. It's not a question:)
According to the Devs, "Nothing has been officially stated regarding which game will receive its patch next, so I wouldn't guarantee that one game will be patched before the other."
Yes there will be. There were things added in the IWD 1.4 patch, like the improved pathfinding, that have yet to be included in the other games. So at the very least we'll see patches that include those changes, if nothing else. I wouldn't be surprised if the IWD spells and Bard songs also make their way into the BG games as well, seeing as how those BG components were added to the more recent game.
Well, BGEE druids definitely need a better choice of spells like their counterparts in IWDEE. Should they add some IWDEE spells for this class, it would be great indeed. However, I doubt they will do that.

So, "will recieve" clearly shows that there will be a further patch.
I kinda hope they don't release anymore, I'm hella sick of uninstalling and reinstalling all the mods.
