A lot of the work will already have been done, which will save time. Most of the stuff they'll implement into JK2 has already been designed for SOF2. The AI will have been half completed, but they still need to add to it for JK2, as the AI will perform differently to most of Ravens other games. Bots will most probably be included, we have seen this done many times before, the one that springs straight to mind is STVEF. The reviewers these days like offline bots.
The force will betray you to me.
