Well, they certainly now have a new market to justify a relaunch. If they are reading this news they HAVE to know the market has opened up for them.
I have been a die hard Roku user (stb only, never full tvs though!!!) since they were first released. I'm not throwing them all out tomorrow, but I will be watching VERY closely and won't hesitate to convert all 3 in the house to something else. Another reason why I never bought roku tvs, I like my tv dumb for just this reason.
