Whatever they mention as a timetable, add 5 months or so. They were talking about the imminent addition of the AK to the weapons tables early march, still hasn't hit stable, even though it was the first fucking weapon shown in the first preview videos rocket put up. Maybe with the addition of an entire studio they've recently acquired the pace of development will change, but I've been with DayZ too long to get even slightly optimistic.
If you're tired of walking, just jump on a 40 person server that's nearly full, put the ocean to your left, and run through Elektro screaming. You're bound to run into something interesting if you survive more than 5 minutes.
IMO DayZ needs a few things immediately-
Server Browser: It sucks ass and largely doesn't work. Saving servers to favorites is nigh fruitless. Half the time the fuckers will rename themselves or just change or remove themselves entirely. If you switch tabs between friends/favorites/main server list, the entire list of servers has to refresh again and you're stuck AFKing for a while any time you tab over. It's just plain annoying and inconvenient, and I don't see why this hasn't been fixed already.
Tents: There needs to be loot permanence so there's not such a huge draw to shoot anyone in the off chance they've got a scope you might need (especially since scopes and weapon attachments on guns don't seem to degrade in combat, unlike everything else on your char). There needs to be storage so that you don't have to live at airfields or military spawns just to get decent weapons, and immediately upon spawn run your ass to military spots upon respawn to regear instead of just getting massacred in populated areas that almost always have been picked over completely.
Loot respawning: Absolute must. There's really no choice but to server hop, or play on low population servers if you want to have any hope of finding gear, or even food and drink at present. This is game breaking, IMO. DayZ becomes a scavenger hunt/loot grind instead of what made it great: an unforgiving, bizarre social experiment with high grade weapons and cracked out zombles.
Base building and vehicles need to happen, but these three HAVE to happen for the game to retain people who aren't just in it to deathmatch.
