Grrrr... Seriously why are there SO FRAGGING MANY changes to German version that never see the official light of day in English?
because CGL 
please be assured that all changes in German Editions are priorily send to CGL .
Pegasus makes/prints only those changes that get an ok from CGL first
Hough!

Has it ever been spelled out in black and white terms that all Pegasus rule changes are approved as errata by CGL?
Not in some namby-pamby mushy indirect "read between the lines" type statement, but in a direct "this is the process step-by-step" statement?
I myself worked on the Errattas for SR4As Fronteinsatz ( War! )
And I know firsthand that we made Erratta lists (Plural) that were send via Tigger to CGL (IIRC to JMH personally but I don't remember 100% anymore)
and Tigger (the German Editor of Pegasus) as well as SirDoom ( one of the Main german Freelancer) kinda pledged to always check everything with CGL first.
It is (I guess ) because the former Company Fanpro ( they made SR2 and 3 ) had too much leeway with their German Branch and them Germans invented/introduced a lot of Impalanced / overpowered Items and IIRC they were the culprits of SR3 Smurfs in Germany .And they (Pegasus) didn't want to make the same Mistakes. They were quite stern about it
(that was one of the reasons I became a Supporter myself )
Ok anyway
I can guarantee you personally ,that we did it in the Past and even though I'm not a Supporter anymore (I stopped at the end of SR4A) I'm still moderator in the Pegasus Forum, I'm still in contact with the Pergasus staff (mainly at Conventions)
and I'm still quite active in all relevant SR Forums in Germany and I think I would've noticed if Pegasus would've changed their Modus operandi ( checking changes with CGL first)
Hough !
