I just had to look up Sabrina's age xD She's 15?!??!?!?!?!

I'm thinking it'll go up to Season 3 on Disney Channel (that's them in middle school), then in Season 4 when they go into high school it'll move to ABC Family or somewhere, where they can deal with the bigger stuff like sex, drugs, and drinking (because that's what BMW did). Plus, ABC will let it go on to Season 8 at least (which would be them graduating high school and going into college).

If it stays on Disney Channel for its entire run, then yeah it won't go as far as BMW.
