GRUB2 in RHEL 7

It looks like RHEL7 will include an updated bootloader in the form of GRUB2. Has anyone had a chance to play around with the new features available in GRUB2? If so, what did you think?

If not, check out http://fedoraproject.org/wiki/Features/Grub2  on the Fedora wiki and take a look at the "what currently works" section. Anything there especially pique your interest?
