Speaking of disappointments, something that came to my mind in the last week or so...
I haven't actually seen the PHB yet, but I've seen lots of previewed page of both the PHB and the MM, and I have been slowly realizing that the biggest practical disappointment is that they look incredibly "light" of material compared to the 3e core books. The fonts are larger, the spacing is wider, each printed row is shorter (don't know if it's just an indentation effect), the pictures are bigger (which is even nice on one hand...), the space between in more. I don't know how many pictures are in the book, maybe they're just showing previews of the best artwork, but overall the majority of pages don't have any? Overall I am starting to be afraid that the 320 PHB pages are worth much less than the 320 PHB pages of 3e, simply because the material contained is much less.
Thinking about 5e as a whole, this may not be a problem at all. After all 5e is supposed to be lighter when it comes to rules, so it probably doesn't need half of the rules, numbers and explanations of them, that were in the 3e core books. But at the same time I know that half of the classes have only 2 subclasses, that some backgrounds were removed, that feats are very few, fighter maneuvers are few, clerical domains are REALLY few, and even the total number of spells is not much more than half of the spells in 3e core (although this is partly due to combining healing, summoning and a few more spells together). And I can't avoid thinking that they might have purposefully padded the 5e books with blank space and used a larger font to cover the fact that they didn't have time to design more material in order to publish the game for Gencon, and to justify the price with the number of pages. But I would have preferred same price, less pages, less padding.
It DOES feel lighter than 3e. But that was their intention, it is definitely an easier game to jump into. Do i wish it had more complexity and a higher page count? ABSOLUTELY. It should be 50 pages longer in my opinion. Take all of that art, spread it out more, and give us more expanded mechanics. Hell, even a few DMG previews of alternate rules or something. But as someone else mentioned, it is brilliantly laid and and infinitely readable, so they nailed that part.
