I checked Expansys.com today for some price info about upcoming SGS2. What I've found shocked me, the price is really high!
It's 649 GBP, which is around 772 EUR
IMO that is not the price which smartphone is worth, on other services the new GalaxyS II is priced around 540 GBP
The release date is said to be 18.04, while Engadget says that it will be out even this month.
