I must apologize that we did poor communication with pre-order customers, and by sending some announcing emails doesn't work really well.
Currently, we can produce around 700 units per week - thanks to the support of our OEM, so we're pretty confidence that pre-order units can be shipped before the end of April.
Most important of all, we will soon release a pre-order survey to let you choose the color of your filaments, confirm again with your latest address and the shipping cost - so check your inbox next week to fill out the survey.
Meanwhile, I encourage pre-order customers to download and play around FLUX Studio ( with VC++ if you're using Windows ), and see if there will be compatibility issue in advance.
Hope this can answer your questions.
