There are some gaping holes out there, no doubt about that. I'm looking forward to the MiG-23 and AvioDev's Mirage F1, they will spice things up on the Cold War server. The Phantom represents a massive missed opportunity, I'm pretty sure people would be lining up to buy it. The Century Series aircraft, while very nice, wouldn't be a sound business proposition for ED - IMHO it's far more likely they'll get picked up by 3rd party devs. I still don't get why the A-4 Skyhawk mod hasn't been picked up as an official module. The Kfir mod also looks amazing, I hope they become a full-time dev.
Oh yeah. It's a shame ED put the AH-1S on the back burner, BLUFOR could use some proper attack helicopters. When it comes to modules, the Su-17 is at the top of my wishlist, right up there with the Su-24 and full-fidelity early Soviet 4th gens.
