As far as an expansion for IWD 2 is concerned, see what J.E. Sawyer (lead designer on IWD2 has to say in the official site:

IWD 2 is the last IE game that's for sure.

As far as Lionheart BIS are not the ones actually doing the design www.reflexive.net is.

The BIS team (including those who finished working on IWD 2) are busy working on a secret, as of yet, unnanounced project, codenamed "Jefferson" it is either a 3rd edition game with a new engine or... Fallout 3 IMHO.

Fallout 3? Dream on! [img]smile.gif[/img]
Rumors of such a miracle have been squished to death by every developer.

BIS has confirmed that there will be no expansion for IWD2 (make it "NNNOOOO!!! expansion"). Too bad...I sure hope the IE source will become available, but i doubt Interplay will ever do so. Or they'll do like sierra and wait 10 years to release a once-good engine for the real nostalgics.

Still stinks!! I understand wanting to move on and develop bigger and better things but the engine has been popular (evident by this website alone) and seems a waste to give up a good thing.

well the real problem behind the infinity engine:

i don't know why, but we as player set engine = graphic engine
the infinity engine is more - it contains most of the AD&D Rulez
and if u exaime IWD2 closer -

it must be incredible hard to "overrule" this part of the engine

and so i think this is the real bottleneck of the engine

it isn't possible to code things like stacked abilities or dual wield with this engine
