We have an ongoing internal discussion if and how we can migrate the weapons, skins and vehicles into the ger celle 2013 version.
The main reason why we cant publish a merged version right away is because the following factors:
pros:
+ having only 1 celle version.
+ it would add a much greater spectrum of variety
+ almost everyone was hot for the changes graz provided.
+ this way we can achive official hive support, because there may be only one celle version at all
+ players will love it
cons:
after the release of 1.7.5 we sadly discovered that not all changes taken where as good as we hoped. glitches and bugs maked it hard to play or to have fun with (in the opinions of some of us)
- players / admins would excpect
us to provide support for broken features (example: the hazmat skins and KK's roll jump) which we did not develope nor have choosen. we did choose the packages we included only after many tests and they get only included if they are 100% bugfree and playable in our opinion.
- only taking the best parts of the mod is a quite difficult process
- the filesize would increase more than the new features would give to the players. 4 more vehicles when having already about 80 spawnable for 300 more mb? (I'm overacting here)
- destroying the initial reasons why ger celle 2013 was released (and yes this is also a sentimetal reason)
I for my part would really love a greater variety of weapons and vehicles with mounted guns. And im already grinding my gears how to accomplish a migration of both mods. But they go in really different directions: player deathmatch vs survival.
But also I have to say we are open for ideas because we wont turn down features which
do work.
Maybe there can be 2 different server versions, based on 1 client version. A more deathmatchy version and a more survival version. In one you could find an m107 in very barn, in the other only after hard days of salvaging.
Salvage script: we did fix its problems and also the DayZ Mod related problem of beeing unable to repair vehicleparts! The reason was that only the 'owner' of the vehicle may do actions to the vehicle and the DayZ Mod team did break everything by messing around with parts which we thing they didnt understand. So the Ger Celle 2013 is currently (I think) the only mod out there which does not have the refuel bug

(but we did submit to DayZ Mod the solution!)
The Key issue: is there? I never tried to run a server with all keys installed. It should work like that: keys for the map are the same. keys for @DayZ_Celle and @DayZ_dgxCelle differ - but also are named differently...
New Tent: I would love seeing 2 different kind of tents!
So summing it up: I would love to see a combined version of celle because I'm stronly on the pro side of my above list. Big question is how do we achive that without pissing at least one half of players off by having reduced loot or the other half by having broken skins which we maybe cannot fix....
