It'll be hard to find some real scoops at Computex this year. AMD will soon be releasing B450 chipset based motherboards that offer a bit more value. below the fold some photos of B450 motherboards o... Multiple AMD B450 motherboards Spotted at Computex
Plan was to multiplex more PCIE lanes using multiplexor chips, but that meant they'd have to design around it, so they had to make sure whatever chip they chose for their design had ample supply because they coudn't drop in an "alternative". There weren't enough from any supplier. tl;dr: They cancelled it due to the fact they couldn't source a reliable supply of PCIE multiplexor chips
Ah ok, so there will in fact be no z490 anytime soon. I was actually waiting on purchasing a new board with the latest chipset but if it’s vapor ware I suppose I’ll just go ahead and narrow my search down to the latest currently available. Thanks for the info
