Full frame or crop sensor topics will continue but I can foresee in the future small bodies medium format camera's becoming more mainstream.
If people discussed mainly doing print then crop sensor is on a level playing field. If high iso gets thrown into the mix the new latest crop sensors are doing a pretty good job in providing nice files for print.
The latest topics both emphasize weight and sensor size in the camera world. If weight is not a concern I'd lug a full frame any day over my canon or fuji crop sensor.
Since I use both sensor types I'll pick and choose whatever the situation. Just recently I've been seeing how I can push the limits of the 5dmk4. As a Canon shooter I've never been able to get away with some photos in such low light. I'm very impressed with the 5dmk4 sensor. However in good light I'm extremely pleased with my 5dmk3 but all of my Canon zooms are now showing a very noticeable improvement/difference in micro contrast/sharpness with the 5dmk4 sensor.
I do find I get sharper family group shots with my full frame sensor over my fuji. This is more of a higher nit pick on computer screen but if I print either fuji or Canon does just fine.
