Finally some direct factory info... (no demos, yet)

They talk as if this is NOT a replacement for the Electro2, but a product that straddles the price point between E2 and the Stage.

Whatever... It still looks like a winner. No news of a Rack model, yet. That would be my preference, I think, but it's early days.
