Tivo Product Lifecycle Duration

Just curious how long the Tivo sells a particular hardware model based on past models.



I have a Premiere XL 2 tuner with Lifetime that I bought in 2012 and I have considered selling the unit and replacing it with a basic or plus. On the other hand, the frugal person is saying sit tight and when new hardware is released, move the roamio pro to the premiere, sell it and buy the latest and greatest.



Thanks,
