I based my nummbers on real market prices, not on some weird RRP, (to which no one follows lately)
But we can look at RRP prices in UK, (if it changes something).
Campagnolo SuperRecord UKP 1990
Campagnolo Record UKP 1650
Campagnolo Chorus UKP 1170
Campagnolo Athema UKP 920
Campagnolo Centaur C UKP 795
Shimano Di UKP 3030
Shimano DA7900 UKP 1600
Shimano Ultegra 6700 UKP 850
These prices has nothing to do with discounted or grey/black market. The Ultegra are in Centaur Carbon/Athema price range, not in Chorus. But of course, if I do good search I can find it for higher price (but why should I).
I suppose that shimano prices will come down as well (those weired $1400 for 6700)
