In addition to @nodrogd answer...
I've (very recently) renewed my VM deal for 18months, and am very much a V6 fan. In time I'm sure the V360 will be a much improved box, but for now... I'm quite happy witth the V6 too - and being an existing customer, I didn't ask for a box-swap and it wasn't an issue.
The TiVo/V6 platform will be around for a little while yet, and I seem to recall there was a similar situation going back, where I had a TiVo and the V6 was the star-product.
All new TV & broadband installs are V360 only. TV-only customers are still getting TiVo boxes, and box-swaps from TiVo > V6 are still actively happening.
