I feel like chiming in. Considerring the timing of the announcement (if it is in fact soon), I am guessing it's someone whose involvement was pending the announcement of the next TV season, which just completed last week. Some possible Hannigan's I can think of that had TV shows in the mix for next Fall that are now free (and some other ideas) are as follows:
Kristin Chenoweth (not my choice, but I could see it happening)
Roseanne (pending her Presidential candidacy, of course)
Allison Janney (this is my pick)
Oprah (yeah, I said it)
Teri Hatcher
Felicity Huffman
Marcia Cross
Sarah Silverman (could be interesting)
and last but not least, Bette Midler. She could use a vehicle to return to Broadway with, her career seems at the right place for a return and ANNIE would be a safe show for her to headline without much pressure of it failing. It's bound to run, whether it's loved or loathed.
