why this game is so expensive?

i know it is always qulity games from blizzard. but with the kotick stuff, i am reluctant to buy it. I missed out to purchase WC3 during my studying days, would love to pay my tribute to blizzard for a job well done for SC2. but kotick appeared.

it just suprises me when there are really lots of ppl buying it no matter the costs. lol...i just feel a bit sad when the publisher decided to milk the fans. because i think D3 will be as expensive too...which is also one of the most anticipated games in my list.
