Before you ask, yes I'm very happy to hear Rips' going to make an appearance (although it likely won't be part of the DCnU canon since it's Vertigo.) Skimming through something I remembered my favorite Rip Hunter section of all time. While I adore all the father/son pages with Booster I fell in love with the opening pages of Rip in the Day of Death arc of Booster Gold. First of all the art and coloring is amazing really setting the mood for the tense moments he's alone with an enemy nearby.
I don't think Jurgens ever revealed who Black Beetle was even in interviews which is disappointing.
