Logitech will start selling the Harmony Ultimate sometime this month, with an MSRP of $349.99. The Harmony Smart Control will follow sometime in April for $129.99.
My first was a Harmony 676, I loved it as well but quit working properly, so I upgraded to the 1100. I've heard lots of good things about the One online - one of the things I'm excited about is setting up sequences, since my 1100 doesn't support them.
There was a press release about them looking to sell the Harmony line - maybe they're releasing stuff to make the financials look better for the potential buyers?
