Salary Cap????

I keep hearing the league will be inforcing the salary cap next season.....
If this is true does this mean half of the Argo players will be available to sign elsewhere....
Will the Argos have to follow the same rules as everyone else or will the C.F.L. be pushing for the Argos to be in the GreyCup at home next year.
It seems to me that the Argos play under a different set of rules then the rest of the league.
Im gonna assume if the Argos do have to play fair they wont be very good next year since they dont devolope talent they just pick up over paid N.F.L
rejects.......
