Just wanted to point out that all Iconic Heroes can be created. Despite still being grayed out, you can create a character. The story lines look interesting at first glance.
PDK has no racial modifiers to stats -- no human free feat (just fighter class feat and initial feat).
Morninglord has -2con/+2int (confused bout the int... not wis?) -- inital feat and racial (read faith, can only chose Amunator...)
Shadar-Kai has -2cha/+2dex -- only initial feat.
Other things noticed, could not chose dragonmarks in "creation forge" at level 1 -- but were available in the test dojo at later levels... not sure what is intended there.
PDK enhancement line is human line with a few perks that have already been mentioned.
Shadar-Kai line looks like a new line of enhancements, but I only had time to glance at it.
Morninglord line looks like exactly the same line as Elf enhancements, again, only had time to glance at it.
I'll post more after work, provided others haven't already posted more details and of course provided that my new iconic's are still there.
