Well from my understanding talking with "Instinct" at the DMS website... the holdup is from 3 sub developers in the mix of 6. The mistake was that it needs to be sent to Aspyr and cleared from them next time BEFORE going to all the multi port subs.
So what will it include? Supposedly just ALL the patches to date SP/MP mixed into one... and a revision on the copy protection.
Why is the next patch already a work in progress? They not releasing the Japanese in this upcoming patch due to they did not have it 100% complete yet... this probably includes new units, infantry, textures, sounds, maps, videos... I am not sure.
I am ok not having the Japanese yet if we hopefully get them soon in next patch... Definately waiting on this next patch seeing atm I am still running the original disc build and don't want to install a SP or MP only patch since I mod SP atm.
So there is not ETA yet on the patch... but they are trying to get it done between 6 seperate sub publishers.. and that alone is quite a mess.
They are listening and working on it though... Patience is a virture (and a wicked cool set of patches coming!)
