From the Reuters article,
Quote:
While DirecTV executives said they were still contractually obligated to continue selling TiVo devices, which let television viewers pause and record live TV, the company said its focus would be on marketing its own devices.

So, at least until that contract gives out, combo unit TiVos will still be supported by DirecTV. After that, it's just a matter of whether DirecTV wants to honk off their customers or not.

My crystal ball offered up another thought. If and when DirecTV tries to obsolete its TiVo userbase, they'll be offering some kind of "pay X and we'll give you the new DirecTV-brand box" incentive. As long as X is a non-trivial amount of money, that's an opportunity for TiVo or anybody else to offer a counter-incentive to migrate to whatever box they're offering.

Should be interesting to see how this pans out.
