I've been waiting for this ever since it was first announced, Renard and the team have done an insanely good job with MGD1&2 so i can't wait to see how this turns out.
I already think that MGD beats both DDR and ITG in both stepcharts and tracklists, and from what i've seen of 3 so far, it's most likely going to take the lead in presentation as well.
And since it'll have .sm and .dwi support, it'll most likely be replacing ITG2 as my preferred program.
The delay's a bit badly timed for me though, the new release date is the same day i'm moving out, and my new place might not have anywhere to put my pad so i might not get chance to try it on foot for quite a while. X_x
Aah well, lookin forward to it either way!
