How low would the price of a used Roamio Basic go once the Bolt line is released?

I am thinking about ordering 2 refurbished Roamio Basic boxes and wonder how much the price would go down on used boxes with lifetime service once the Bolt line comes out? If the Bolt line comes out during my 30 day return period, I could just send the Roamio Basic boxes back to TiVo. If not, then I am stuck with selling them myself. Right now the resale value is great, but I wonder how that would change once the Bolt line is released?

I called TiVo today and could get a free Slide Pro remote with my order and this would effectively price the Roamio Basic boxes at $275.00 each. I could probably place 2 separate orders and lower the effective price of each box to $250.00.

I would really like to see what the Bolt line is going to offer, but I want a box that gives me the option of OTA or cable, just like the Roamio Basic does now. Not having this option might be a deal breaker for me.
