Hmm. I like most of that.
What I find most interesting about 4e, as it gets closer, is that the developers are much sharper than the pro 4e fans gave them credit for being. Consider, for example, the HUGE frackin' thread on succubi and the apparent belief that, in 4e, things like "How does a vampire make other vampires" would be wholly ignored (and that this was a good thing). Well, looks like it's NOT -- there are actual rules/guidelines for it. Good.
I like the artifacts information, too. Sounds like it's designed mostly to inspire DMs to create their own. A few solid examples to serve as guidelines, the rest is up to you.
Alignments-- well, that's been totally borked up one side and down the other, but since alignments no longer matter (much) to the rules, it should be trivial to add them in -- and add in axiomatic and anarchic energy, as well. Houserules FTW, and depending on how the GSL is written WRT access to the old SRD, it might be easy to add them into commercial products for those who want it.
I like there are still effects which aren't "save ends". I was worried, based on things like the phane, that NOTHING would last longer than a single encounter.
Between this info and the general non-suckiness, rules wise, of KOTS, I am actually beginning to look forward to 4e. I don't see how I could convert my current game, but it might be fun to begin working on my next campaign. (Some people have backup characters; I have backup worlds...)
