You have to remember that the current F-150 is will only be 4-5 model years (depending on the way you look at it) old when it's replaced, which is very quick in the truck world. I'd say all new sheetmetal, new interior, engine upgrades/new engines (at launch/following launch), new options (tailgate step new post-cab bed step, integrated trailer brake system,....etc.) is a pretty significant upgrade for a 4-5 year old truck.
That said, on the vehicles you listed above, Ford did drop the ball, but IMO, Ford won't let that happen w/ their bread-and-butter F-series.
