While I cannot comment on how quickly ED will have BS, Tank Killers or the fighter project out (and I'm really keen on the fighter project! ;) ), it seems as if ED and FO will be in direct competition.
Both seem to be putting excellent offers on the table, and I believe that this is a good thing . I will likely have both sims on my HD!
Also, as far as avionics fidelity goes vs. F4 ... i don't know. I think the Ka-50 is pretty darned complex as is, just for navigation systems alone.
Although I believe it may not model every single switch like F4 does, on the -other- hand, pilot workload, IMHO, is very realistic, as is the immersiveness of the 'pit itself. Not -only- do you have a -lot- of switches to play with and they -do- do something, but the interaction between polayer and cockpit -rocks-.
And I -cannot- stress enough how -awesome- 6DOF is.
If your wingman hiding behind that pesky canopy frame? No problem!!!
Move yoru head to the side a little and there he is!
need to see over the nose for that landing? Move your head up!
Need to look over your shoulder?... Guess what ... you can :D
