Retail gear is totally unrelated and irrelevant to epic perfect world and current r8r is not going to be replaced. There is many important reasons for that and I don't think that I even have to list them.
Just FYI according to some PW scene dev. - some p.servers already have 1.5.2 files so its matter of time till we see an server with them. We'll have p.server with 1.5.2 and new classes before PWI.
Unless there is someone that wants to go in and translate all the files related to the new content, which I doubt since most devs and stuff dont get hardly any compensation out of it, then I seriously doubt there is an ENGLISH pserv with the files. And, even if they do have them, they will be buggy, they will be incomplete, and because of the translation issues, Its going to be AFTER PWI gets this update before any English pservs get it. And, even then, that will take a while. It usually does take a month or so before any pservs get new updates and get them implemented from PWI. IJS.
bumppp
Files were acquired by russian pserver owners and theyre being sold as we speak (the info is coming from Bash). Trust me, things well be translated so fast cuz there lots of money to be made outta those files.
