I received an email from Cyril BERREBI, Gaming Communication Manager, in response to an inquiry I made about a physical release for adventure game collectors. Here is his response:
"thanks for your interest in subject 13.
retail versions are planned and should be released in some countries.
in which one are you ?
I'm collector myself so i understand you prefer a retail version :).
have a nice day."
The US is one of those countries that will get a retail version. I know I am looking forward to it.
