Rumour has it that WAS are busy working on a force-fed hopper called the Corkscrew - supposed to run at 30+bps (at least that's the fastest he can get it before it just smashes paint) but don't hold your breath. Mr Drew has never been great at getting products to market in a timely fashion.
Apart from that, Odyssey are just starting shipments of the TSA (in four different versions*) - agitated like a revvy, except they spin in both directions, depending on which way they are tilted. Oh, and they seem to have started shipping HALO motors that look like they won't burn out in 5 minutes.
And there's the Egg's Y-board - the product that BE has confirmed doesn't exist, although that's not stopping them from happily marketing it.
How many hoppers can you need?
(*) QP pointed out the obvious flaw in Odyssey's Backman/Frontman logic - it doesn't matter whether your hopper holds 175 or 220 balls, you're still filling it from the same 140-round pots, so you're still potting up just as frequently
