Here's info posted on another forum:
We are consolidating the inventory
There will be 12 pcs 90W Kits available this Thursday-Friday.
There will be 60-75 Boards available this Thursday-Friday.
We have very few Board heatsinks left. 10-15 pcs. Will be available by Friday.
We cannot accept pre order on Board Heatsinks as quantity is too low and we dont know how many we have left.
More QB304 boards are on order and will be available 3rd week of Jan. There are limited 4000K boards too. If someone wants 5000K then let us know asap
We have 2 suppliers making heatsinks and so heatsinks will be restocked soon. 3rd week of Jan.
We are also designing a new heatsink that can hold 3 boards. Like a 3x of Slate 1
We are also designing a new version of heatsink for single board that will be around $20 and can handle more power.
