Good idea for a thread, and these are all great questions. 

The only one I would add is this: it would be very nice to get some idea (even a hint would be great...) of some of the Classic (i.e., reprinting '60's-'80's material, though these days some may even define '90's as "Classic") Omnibi that are going to be coming out in the next several years.  In the past year we've obviously seen these great Omnibi: Walt Simonson Thor, John Byrne FF Volume 1, John Carter, ASM Omnibus Volume 2, and the forthcoming, highly anticipated Man-Thing volume scheduled to hit this Fall.    So, will there be a John Byrne FF Volume 2?  A '70's Horror compilation (SOS, BV, etc.), Werewolf by Night, and/or a Frankenstein Omnibi?  Or, my personal #1 most wanted Omnibus, Classic Moon Knight by Sienciewicz/Moench?
