Meaningless-but-fun ABC Family suspense series Pretty Little Liars returns to the tube tonight, January 3, at 8pm ET to launch the second half of its successful freshman season.

The first episode up in the shiny new 2011 year has the curiosity-inspiring title “Moments Later.” The moments in question are those following Hanna’s fall season-ending date with a car, and the terrifying incident apparently represents the end of the “nice” A era. Now the anonymous texter known only as A is ready to kick her (his?) harassment up a notch and become even more threatening. Smells like really good times are on the way!

But wait … there’s more. Fans of entertaining ABC Family college dramedy Greek have something to look forward to also. The series begins its fourth season on January 3 at 9pm ET, immediately after the return of Pretty Little Liars, with the premiere episode “Defending Your Honor.” Sounds tense.

Check out the network’s promo for the new Monday-night matchup of its two popular teen-oriented shows below.

Today brings bad, sad news for fans of ABC Family’s science-fiction drama Kyle XY … if it’s true.

Entertainment Weekly is reporting the network has decided to cancel the series, currently just three episodes into its ten-episode third season, presumably because of declining ratings. *sigh* Wouldn’t it be great if we lived in a TV world where those kinds of numbers didn’t matter so much?

On the upside for ABC Family fans — although probably not so much for those who just like Kyle — the network has also reportedly renewed the urban drama Lincoln Heights for a fourth season of an as yet unannounced number of episodes. In addition, the college dramedy Greek is said to have a third season of twenty episodes on its plate.

Both entertaining shows really deserve the vote of confidence, so I guess two out of three is better than one out of three or none. And, while it’s still early days, I predict Kyle XY‘s Monday-night companion, the freshman hit The Secret Life of the American Teenager, has nothing to worry about in the renewal department, either.

That leaves just The Middleman to worry about, I believe. Fingers crossed ABC Family will have the guts to hang on to at least one sci-fi show.

Reminder: ABC Family’s fun college dramedy Greek opens its second season tonight at 9pm EST, and longtime fans are in for a great premiere.

Not only will viewers get to see the young men and women who make up fictional Cyprus-Rhodes University’s active Greek system compete in the gender-bending 63rd Annual Greek Week Olympiad, but Buffy the Vampire Slayer and Angel veteran Charisma Carpenter returns, as well, to reprise her role as Zeta Beta Zeta alumna Tegan Walker. It truly is a good time.
