Here's the issues you mention:
5) Serious Lack of Digital Tools.
4) No PDFs (except for the basic game)
3) Nothing Much to Look Forward To/Lack of Product Diversity
2) The Waiting
1) No OGL (or some kind of compatible license).
Now, number 4) wouldn't really be a problem if it wasn't for 5). The players in my group trying to play spellcasters find this really annoying. You basically need to know the spells by heart, write some sort of short-hand version of your spell or just spend ages each session flipping through the PHB looking to see what your spells does. To sum it up, this is really annoying, and that is already at level 3!
3) and 2) wouldn't really be a problem if it wasn't for 1). I am mostly waiting for.... adventures! Sure, there is a huuuuuge load of adventures from previous editions, but I would prefer a bit more modern design. Something like Red Hand of Doom would be awesome. (Already ran it in 3.5). The current adventure paths seem uninteresting.
Now, personally, I am pretty sure 5e will be the edition I will be using. I have a 4e campaign I am running, but it's easy to notice how slow the combat runs in 4e compared to 5e, even if I am a total noob at running 5e. I will probably use either some unlicensed third party adventures, do a conversion or make up my own stuff. I really miss a character builder (or, at the least, a spell cheat sheet) and a license for third party publishers.
In short, my interest isn't waning, but I understand your issues. As a third party publisher I would be more than a little annoyed. Pathfinder has such a good market share because of the amount of DM material they publish. How come WotC doesn't see this?
Addendum
Yeah, combining the best parts of all the editions (including the "feel" of 1e, i don't know how they pulled that one off) was a great idea. And I like that the system is simple yet robust enough that it can be tinkered with endlessly by DMs and not crumble immediately.
Well said!
