Not really. They are spec'd well enough for some years now to perform most common tasks well and conceptually they are all basically a big touch screen, nothing new here. You may get small improvements, bigger numbers on the spec sheet and flatter models because "look we can". You may buy a new one for whatever specific reason but it's not you miss out sth. substantial with a bit older model.
