I've just read the announcement the euro-prices are raised with around 20% on the 4th of June.
Seeing the euro-dollar exchange rate it's around 1 dollar = 0,75 euro for the latest months, which is also around the long year average.
When seeing the current prices
22k points for € 150,- which is 147 points/euro
23k points for $ 200,- which is 115 points/dollar
If I compare these too you get an exchange rate of 1 dollar = 0,78 euro, which is even higher then the current exchange rates, so the current price lvl is a little too high, raising it with 20% makes it way too high.
If I compare it from another viewpoint, the exchange rate when f2p launched, which is september 8th 2010, the exchange rate was 1 dollar = 0,78 euro, whisch is almost the same exactly the same as the current exchange rate, so this also doesn't support a price-raise for the Euro-prices
