The Congo is roughly on
par with the
Eos (Obsession), the Congo jr is roughly on
par with the
Ion (Expression), and the Congo Kid is roughly on
par with the
Element (
Express). So no, the Congo jr was not the
Express of that family.
The item under the bed sheet sure does look like an
Eos so I'm not sure the photo is actually much of a hint since I can't imagine them releasing something with such a similar form factor but who knows. I do feel like the price differential between the
Element and the
Ion is small enough that I can't imagine them putting another product between those two without it completely cannibalizing sales from their two existing products. I think something between the
Eos and the
Ion is more likely given the price/hardware difference between those two. Maybe an
Eos without the screens and with a more
Ion sized
channel capacity?
