As you know, Ultrascale is a one-man band. I've never seen a wait time shorter than 5 months. In many ways, he's a victim of his own successful products because, as soon as he manages to reduce the lead times, word gets round and everyone piles their orders in, leading to an immediate lengthening of wait times, sometimes longer than previously!
It's not inconceivable that customers have dropped dead before receiving their order...
