To all who are interested and didn't recognize it yet
Thanks - still no 6d unlike in the US, so lucky me I bought it for ~1500€ and the price has gone up since then :-> ... and it's funny to see that there are more months of the year *with* Cashback in Germany than without, so basically you have to be in a real hurry to buy these for the full price.
Btw. These cashbacks are less than the last, I got €100 on the 600rt, the 24-70L2 was €300 instead of €250 now...
... and I missed the chance to sell my 430ex2 via ebay in the short period w/o cashback
