Reference link is on the FFG home page. Nice to finally get this and it comes with 6 dice as well (more than the core box) which is a deviation from standard dice packs.
Dice Pack is Here Finally!
Very glad to see them listen to us 
Let's see ... hundreds begging to spend money with FFG ... FFG produces item beggars want ...
FFG selling plastic crack ...
Take my money ... please ...
Three sets of those please.... 
Well needed! Finally! It's a shame we'll have to live with an uneven total amount of dice, but I suppose I can pick up two packs and toss a die.
This seriously made my day! Nice!!!!!
Happy to see this. Just played with a full group last weekend and definitely felt the need for more dice. Will pick 1 or more packs up at release.
Going to preorder 3-4 packs of these ASAP.
Hi, I'm really looking forward to be buying the franchise and wondering why a 2nd dice pack is useful? Can anyone shed light on why more will be useful?

Often your character will be able to roll 6-7 dice, which means rerolling 2. People also just like to have 1 set for each player so you don't have to pass them around the table.
Handy tip if you also play X-Wing and are on a budget: Mansions of Madness dice have the exact same face distribution and layout as an Evade die with 3 success (elder sign / evade), 2 focus (magnifying glass / eye), 3 blank.

I think that "often" is a bit of exaggeration. I played 9 games of MoM2 and remember only 2 instances when we had to roll more than 5.
Just take an investigator with an attribute of 5 and give him one of the items that grant +1 to this attribute from the start. You will roll at least 6 dice all the time, whenever this attribute comes up...
About to get greedy here...but I wish they came in about 4 different color choices!
