Aha! Just as I predicted! They did an update detailing a selection of Assist Trophies, including three they had mentioned before in passing. Finally, though, clear pics and art for Jill and Metroid, and our first real glimpse of Kat & Ana and Helirin! I'm going to assume in a few weeks they'll give us 'Assist Trophies, Part 2' that will include Barbara Bat, Infantry, Isaac, Shadow, and Ray.
It's good to see stuff getting done around here!
