Very good news on the PHB races, I think. This way absolutely everyone is covered, which is in-tune with the "D&D for everyone" deal WotC have pushed re: 5E.
Interesting too that it seems most races have at least two "kinds" to choose from - this could also really help out, providing us with, say, a 2E-style Tiefling and a 4E-style one. I think four kinds of elf would really cover everything - High, Wood, Tricksy/Eladrin/Moon (there are plenty of other settings which have a "Tricksy" kind of elf known for vanishing into nowhere - Taladas, for one), and Drow. I'll be interested to see if the PHB defaults to the FR descriptors or more generic descriptors (presuming the latter).
Like Kamikaze, I'm intrigued by the class building guidelines, that could be one of the most interesting, or, of course, most entirely useless, parts of the book (2E's class building was a horrible mess, but did at least let you build the Kai/Magna-Kai if you were willing to spend 3000xp to reach level 1!).
In general the information seems very positive. I'm skeptical of some elements of 5E, but the overall thought put into the design and release seems to be very solid, perhaps more solid than any previous edition.
[MENTION=98772]Ichneumon[/MENTION] - I very much doubt that we'll see anything like Battlesystem, or that a smaller number of high-level monsters means we'll be fighting large groups of them (if that's what you meant). More likely, we'll be looking at a 2E kind of scenario, more often than not, with one or a small number of really serious monsters, and a between a handful and a few dozen henchmonsters of much, much lower level, but who are still a threat in large numbers because of the flatter math. 2E never needed special rules to deal with that.
The only worry there is that, in 2E, to deal with that kind of scenario, you generally needed a caster capable of putting out a lot of AE damage (unless the monsters were less than 1HD, in which case a Fighter was fine if a little dice-intensive!), and I don't think it's really viable to hard-require that in this day and age, especially when they're providing a such a wide variety of classes, and so few of them can deal with AE situations well. So if that's the default they will probably need some "cutting a bloody swathe"-type rules for classes with multiple attacks hitting blocks of enemies with sufficient level difference.
