First of all I'm new here, so bear with me if this has been asked, but I couldn't find any info about it through google searches. So I'm about to take the plunge and order a new Apple TV, the only thing I'm iffy about is the future of iTunes. Before I start buying hundreds of my favorite movies/shows in 1080p from iTunes I want to be assured that when the next best thing comes along.. which is already here pretty much and is called 4k tv (a lot of films are being filmed in this now) will Apple/iTunes be offering free upgrades of my 1080p collection? I mean it's inevitable that the 1080p will become obsolete in the years to come, probably sooner than later. What's your take on this do you have any info? Thanks a million if you reply.
