[I might be late on this discovery, but thought I'd share]
There were multiple heated comments earlier today about skills not appearing in Fallout 4.
The biggest piece I found to go against this is that when you pause the E3 presentation at the "Settlement Building" portion, you can count the number of bobblehead slots on your bobblehead stand. There are 7 for the 7 Specials that you can see immediately. In addition, there are 13 other slots for what I assume to be the skill bobbleheads.
Another point is that when we are shown the new pipboy feature, the screen starts on stats, and there is a toggle to go through the "Stats" portion of screens. Perks is hidden when the player character initially opens their Stats menu. However, they scroll one section to the right and Perks are now revealed, although not highlighted. My best guess is that one more toggle to the right will reveal the skills section, which is easily hidden by this new condensed user interface.
So there's my 2 cents of digging into the videos. Thought this might help cool down those of you who got into a tiss earlier about skills not being in Fallout 4, because these two points have me fairly convinced that Bethesda didn't cut them out.
Can't help about the dialogue issue though! Still looks like a condensed Mass Effect dialogue wheel, but hey, we got jetpacks!!
