I'm not going to go into all of the boring details, but on Marvel's "Next Big Thing" call/blog they detailed Loeb and McGuinness' exit from Nova after issue #5. Taking over will be Zeb Wells and Paco Medina (Medina's design is on the right).

Loeb covered in boring detail what the remaining chapters in his story would cover and alluded that the series about Novas, not just Nova. The rest of the info was generic marketing crap and pretty boring. What's up for Loeb and McGuinness next? Nothing announced, but there is something in the works! Can wait to see what Loeb puts his dick in next.
