Its cool. Even without a reason ( although granted this is a good one) a delay by Blizzard Entertainment is frequent, normal, and always expected.
We can only hope that this means we're actually getting real well-thought out positive responses (or they could just be messing with us you know?). *If* they actually are ill though, we should wish them well since they are the core of the game.
The problems with this game are not 100% their fault, I'm sure there are business folk at the top who deserve a lot of the blame for the bad directions this game has taken. I'm glad they posted this, now I have an idea of why the PTR/patch 1.07 is taking so long. Hopefully once flue season is over, they'll be able to put out patches faster.
Thank you Diablo 3 development team, especially coders, for your hard work, we wish you well. We hope you feel better soon.
~Gamers like me who are only actually 1% jerk and 99% good intentions (it just seems the other way around).
PS: Don't get *too* close, we don't want your zombie plague upon us!
