Toywiz started shipping them a few days ago, along with a few other websites. Right now they will primarily be invading hobby stores, with plans to release them at the big retailers in a week. Unfortunately they are only available in the USA and Canada right now, but hopefully we will see them pop up overseas in the coming weeks!
Now go buy them and send me all the foils and Trixies. I require a full set for free! Get on it!
