I just hope they keep it to where supplies are scarce and it is more about survival and desperation. Originally when I played DayZ every bullet was important and if you saw someone you either tried to team up or tried to stay hidden. Eventually it seemed that everyone had full assault rifles with almost unlimited ammo and it just became PvP with zombies in the background.
It would also be nice to have some kind of end game or way to encourage teamwork. Building a village or a settlement or something, protecting it from zombies, going on supply runs, etc. Probably hard to do when random people hop on and off of a server, but otherwise there isnt' much of a point to playing for me. I had the random scavenging experience in the original DayZ, don't need it again with a few added features.
