Well, that's sad, but understandable considering how big a deal it is to have a tournament in the WNF umbrella. Means Fridays are pretty free except for RAMnation, but that's been postponed for a while too.
I agree it is really sad because a) the UCI guys are awesome and put in a lot of effort to setup the venue each and everytime (it's not an arcade remember) b) the venue itself is, geography aside, the most ideal with free rent (as long as there's a "club" from UCI), tons of chairs and table and more if you request c) you can be as loud as you want essentially d) pub downstairs for those who need a break e) super fast internet for streamers (20MB up).
However, it really only catered to the Orange County folks and the LA peeps like Team Chaos never made it out. Also, although 7pm start time is pretty standard for a weekday, you just can't beat 9pm in a more central location.
Lastly, the lure of Evo seeding points is kinda hard to turn down.
