All I gotta say is that if the Roku DVP gets discontinued, so goes the life of a modern electronic device. The average technology lifespan for something like the Roku is 3 years, and then there's usually an upgrade in store. Look at Apple- they release a new iPod once or twice a year, and within 2 years, you've forgotten what they did in the past.
The DVP/Netflix Player (or whatever you'd like to call it) is going to be 2 years old next year, and I'm sure a new Roku box will be introduced by then. As the new box will be faster and fuller-featured, more people will eventually migrate to it if it's a better product.
This is probably the reason why Roku isn't updating the core "workings" of the player, and instead focusing on adding 3rd party channels that will probably be compatible with their new DVP when it comes out.
Yeah, I got some Rokus.
