We don't need explanations as to why Banshee and Emma Frost aren't around. We may get hints, but it's not needed.
My sentiments exactly. It's not like there were any open-ended questions hanging out there for Banshee and Havok. It's not like we have this "cliff-hanger" involving them and we must have them all back in the sequel to tie any loose ends up.
The truth is, neither Havok nor Banshee (or any of the others being dropped) are among the most popular, upper echelon of X-Men characters. They just...aren't. And believe me when I say...the main movie going audiences are NOT going to miss them. They are going to be focused 100% on the main core again: Wolverine, Xavier, Magneto, Storm, Rogue, Bobby, etc.
