So if your a F2.8 II owner I wouldn't be swapping.
Kinda regret selling my 2.8 II now, particularly because the distortion looks worse, and it's not a lot sharper. I am looking forward to the smaller hood and I always have my TS-E 17 & 24s for architectural stuff. I'm also curious to see what IS does for me in practice. For travel, I think it will be really nice. I'll have it on Monday...
I'm not sure its really worth regretting, I mean you said you didn't use it at 2.8 anyway and its not like this new lens is worse at landscapes - it is still better, just not as dramatically as the MTFs suggested. On the other hand, the bulk of those improvements are at f4-f8 which is generally just a bit more wide open than most landscapers shoot to max DOF. f/11 seems to be very popular for landscapes and aside from the CA it is almost a tie (the f/4 is ever so slightly sharper in the mid frame). Still, if you didn't use 2.8 you should get some improvements out of this lens. Worse comes to worse you can always return the f/4 lens and buy a used 16-35 II for probably the same price you sold yours, but I am not sure that is the best move - depends on whether you want 2.8. Also, this is my subjective opinion, but I find the 14-pointed sunstars of the 16-35 f/2.8L II more realistic and less distracting than the 18-pointed sunstars of the 16-35 f/4L IS. 18 points of light just looks a bit too busy and almost cartoonish to me.
So, while it may not be the lens that moves heaven and earth as the MTF suggested, for your usage it sounds like it will be an upgrade, albeit a smaller one than expected.
Regarding IS, I have done tests with the 24 IS, 28 IS and 35 IS at slow shutter speeds and was disappointed in the results - compared to say the 70-200 IS II where IS makes a massive difference. Namely, IS on the wide angles did not seem nearly as effective as on tele lenses (less stops of effectiveness) and it was better to just use a tripod for max sharpness at such slow shutters. There were less pictures that were garbage when IS was engaged with super slow shutter, but the "keepers" were not nearly as sharp as they would have been out of a 70-200 with a similar # of stops (or on a tripod) to the extent that I did not find it particularly useful outside of video.
Also keep in mind this is only one review and if you look at the 50L results from the same site you will see they look dreadful. So it is probably worth waiting to see more reviews and real life shots.
If you ever pick up the 16-35 II again there is a trick to storing the hood. Don't flip it in storage position, take it off entirely and place it vertically next to the lens
I also noticed the hood goes on smoother if you grip it by the short fins instead of the long fins, likely as the leverage of the latter deform the hood slightly when twisting.
