As I read and think more about this, I can't help but think there is something else going on here that is not being divulged. Did Yahoo! backout of sponsoring? Did Steamwhislte say no more to the use of their facility? Did other funding fall through that you are not mentioning? It just does not seem to make sense to me, and it's a massive mistake.
Dead-on. The 2009 RPSWC itself wouldn't have happened if it wasn't for Yahoo!. Obviously, it has costed the Grahams a lot to arrange the event throughout the years (just watch the RPS Doc.). Yahoo, as the main sponsor, has probably backed out this year, leaving the Grahams no other choice but to cancel.
It's a shame. I was really looking forward to a tour overseas for this years WC...
