Yesterday's ODROID-H2 launch was extremely successful, in fact all 2,000 units sold out within hours. The bad news is that a second batch isn't coming anytime soon. Hardkernel just confirmed the Gemini Lake scarcity: "Due to Intel's serious supplying issue these days, they can supply the Gemini Lake SoC in February or March 2019". Given Intel's manufacturing problems, it is rumored that TSMC could take over production of Jacobsville, Gemini Lake's successor.
