I have searched a lot of info about Viggen since I heard the rumors that Leatherneck is working on a Viggen module. Just have to say that I am very happy that Leatherneck is working on AJS-37 and I am looking forward to see the result!
In my search I found a document describing the aerodynamics of Viggen on NASA Technical Reports Server (NTRS):

I don’t think this have been posted here before and I hope it will be of interest to some of you. It describes a lot of the reasoning behind the design decisions. There is also some comparisons to F-5 Freedom Fighter, Mirage III, F-4 Phantom and Saab 35 Draken on page 122 (PDF 127), might be some more comparisons but this is the only one I bookmarked. Everything in the document is in English except the figures.
