Is this information available somewhere officially? From what I read it looked like you just had the option of running a game with simultaneous moves or traditional.
About hot seat. If you can only do simultaneous moves then it will be hard to have hot seat considering you wont see anything on a small TV if you are going split screen in a strategy game. The only hot seat that would work is that you take turns sitting by the computer and that what happened while your friend was playing is replayed for you.
The only hotseat I want is to play as allies with my friends though, and then you don't have this problem since you are both working together. It shouldn't be hard to include this feature really and they should really allow the traditional way of playing.
In the official 2kforums in the question & answers thread one guy says "Yep, we should have hotseat" while Elizabeth answers on a question about online hotseat something like "no we wont have hotseat multiplayer". What this means I don't know, I can only hope that it means hotseat is still there but that you cannot play online with it since it would be strange with 2 players using the same network account. But still you could have unranked matches like this. It is starting to become a trend that developers do not include small features that really matters to some people and that wouldnt cost them too much time of development.
And hi everyone
