Not likely. There will always be an opportunity to make money on higher end theaters. It may end up as a smaller market, but it will not go away.
On the flip side, the technology for putting up a calibrated image will continue to get better and easier to use. For the technically literate, it is possible to do a reasonably good DIY calibration with low cost equipment.
Along with this, the out-of-box calibration will get better (when you flip from torch mode to cinema).
It will be easier to get good image and sound quality, but more expensive to get that last 10-20% out of your system using a pro.
