I got the book !
It's definitely a must buy, it includes a bunch of color pictures including cockpit pictures. The profiles are very nice and along with ultra detailled profiles there are a lot of mini profiles a bit like the ones you could find in the Hikoki books, there are quite useful for gettting a general view of a camouflage or specific pattern.
The analysis seems very good but i haven't got time to check it thoroughly yet. A nice addition is of colors used by staffeln and a list of known 190D-9 losses.
A very good buy indeed, and i got it a fairly low price of 35 Euros !
I highly recommand it, impatiently waiting for the next opus
