The game is 90% there, other than some imbalances in the core design, i think once the Tap glitch and some map glitches are fixed the game would be just fine.
Still, not entirely my cup of tea, but it will be very solid.
Crytek has stated several times they are working on fixing the tap fire-no recoil bug, and there are solid rumors about a DLC. I guess they plan to release both at the same time. The patch is taking quite long (it sometimes seems like there are only 2 people working on it, LOL), but I think it's going to happen.
Let's be honest... with less than a 1000 players on at any time, the game is already dead by AAA standards. I'm don't really have any problems paying a couple bucks for some new game modes and maps.
