I let you know way back in january that it cost more than 15K though!
At the time this was begun the price of NXT was half what it is today, you wont get professional players who get their livelihood from this game to play for a couple hundred. And of course casters cost money.
We agreed on sending 15k. If the price of nxt was half, you could wait for few weeks, there is no reason to rush such events.
