Uhm, Psych returns in January with 7 all-new episodes.
Until then, reruns of Psych will air Thursday nights at 1 am /12c
The split the season so we fans don't have to wait a full year to watch it. This way we get to wait 4 months instead of 12 months.
Monk does the same thing..
Shows like Dead Zone and 4400 however go by a Summer Schedule, meaning they only air one time a year, during the summer.
