Kind of like when that one computer designer guy said that no one would ever need more than 4MB of RAM in a personal computer? I wouldn't discredit any new technologies just yet, we have no way of predicting what is going to be avaliable with regards to source technology many years into the future. Hell, there could be systems in 10 years that run 10kx6k resolution or something insane. Always gotta leave ambiguity in the picture and remember the past history of this kind of technology. I don't think we will ever reach any kind of technological plateau for this kind of stuff.
