Thq
 

Seeing as they have DF as an inactive title... you think we will see a revive of the title?

Not sure about an official one from thq but there is a studio called Red Jake Studios that is making a df spirited game that might fill the gaps. On my phone so I can't find a link but if you Google Red Jake Studio Delta Force you will probably find it.

Red Jake Studios is on Facebook and they post updates on that page about the new game "Delta Force: Leave No Man Behind". It is worth joining the page and following!
