Merric,
Does 4E seem more like D&D, than 3E? In short, no. It is the same, but in different ways.
I like a lot of the released info for 4E. Of course, it is in a vaccuum, so my feelings may change. Not having the 3 combat workday will be more like D&D. The never ending gearing up of magic items to be at acceptable power to face an appropriate CR will be more like D&D. The flavor is a mixed bag, it is completely unlike D&D, but it makes it feel more like D&D. I really can not explain that any better. It dumps the specific but retains the spirit I guess.
Ways 4E will not be more like D&D. Tieflings as a core race in PHBI. I have no problem with tieflings as a playable race, but there were much better candidates for replacing the gnome. Changeling tops the list. Much more well rounded trope than the touched by a demon tiefling or even the half-elf. I guess PHBII will have to suffice.
The whole at will/per encounter and per day mechanic is less like D&D. I like the mechanic idea and believe it will improve the game, but it is significantly less D&Dish. The whole flavor change of the cosmology is less D&D. I think this is the biggest and best change for 4E. The Great Wheel has a lot of nostalgia attached but it always seemed like plotting points on a graph than a setting. Ironically, I think a Planescape campaign in the new cosmology will make much more sense. Heresy and talking out my rear end, I know, but after the cosmolgy article I finally became interested in Planescape.
In the end, 4E is another stab at D&D. I like 3.XE but I have played through a couple of campaigns and it is time to move on. There are problems in the rules that I have houserules for or really contorted work arounds. Within a few months of 4E's release I will have started a new sheet of houserules and work arounds. This is what will make 4E just like all the previous editions. The same but different.
