i could see a Gen 4 coming out but not an RTF. I dont think many people would enjoy the RTF in a SC frame because the grip will tear up ones side while carrying iwb. Also while the RTF was a cool design, i do not see it having much lasting power because i think more people dislike it then like it. Some people are turned off by the frame texture and more people are turned off because of the fish gill looking serrations
I often carry my 21sf rtf2 iwb. My sides do not have large bloody holes in them. I doubt anybody who complains about RTF2 has ever carried one. And if they have I doubt it was for more then 1 or 2 days. Yes the RTF2 did bother me the first 2 days but after that it felt fine. I can carry it IWB without any problems now. It was just extra sharp the first few days till it got slightly dull enough to be comfortable. It still has an excellent grip on it. And the Fish gills are gone, They come with the straight serrations now. If they do come out with a G26 RTF2 I would sell my left nut just to get one. But thankfully I have other things to sell instead.
I hate the wait! I am looking to purchase one or two more GLOCKs, and don't want to buy the Gen 3 if the Gen 4 is coming..... I would imagine that all the GLOCKs will get the Gen 4 makeover, but having to wait is tough!
