We likely will, but we are wanting a healthy selection to start. As well as the 'traditional' USMC, British Army, PLA and MEA from the original BF Evo, we are looking to include the Russian Army and US Army - plus, all armies have a lot more units and options now.
So, not a huge number, but enough to take our attention away from other ways of playing the game, which really would require significant work.
Plus, by devoting Spec Ops to another supplement, we can also look at including WWII and SST (and other BF Evo variants) into the mix, rather than just focussing on Modern Combat - in effect, it will be a supplement for all games, not just one.
