Connie chose to leave, as far as I know, because she'd been in the show for a year and a half and wanted to branch out to other things. Her contract had already been extended a few times, and I guess she just thought it was time to move on. There have been various rumors about her possible return, but she seems to be happy in They're Playing Our Song at the Menier right now.
As for Summer, I've seen clips and was distinctly underwhelmed (and I've liked Summer in other things).
