This thread makes me far too happy, so I'm going to give a sensible answer and shut it down.
Because of the financial crisis and "creative differences" with Vanguard Animation, Lorne and Co. have stopped concentrating on Citizen Siege, but they still want to do something different before they return to Oddworld. The company is now called "OddMobb", which has a
number of trademarks that suggest they're planning something ambitious.
In the meantime, the existing Oddworld games are being made available through digital distribution. AO and AE are now available on the PC and (in the US) PS3/PSN, with MO and SW hopefully coming to both later on.
