I haven't heard anything about mods being included in the official version of BG2:EE. There has been some talk however about certain mods being available quickly after release in compatible versions (like the ever-popular SCS or Ascension mods). For the exact data we'll have to wait and see.
I'm sure the list will eventually be updated by the time BG2:EE comes on Nov. 15th. It's also worth noting that many mods for BG:EE should theoretically be compatible with BG2:EE as well.
