Where have all my tv shows gone?

During the summer my sister and I started watching Kyle XY, and Three Moons over ord, and after a few episodes, that was it. Does anyone know if they were moved to different channels, or comming back soon? Also on the New CW the show RunAway was on for about a month and that was the end of that one too it seems. Anyone know anything? or a new 7th Heaven anytime soon???
