This is straight from the exec,here is what he said:
In answer to a question, there will be at least 18 episodes in Season 8 but there may be 22 episodes... we're working on it--if it's 22 episodes the last four will be **special**!!
Pretty much every one will be back, but we are also introducing some new characters so that we can continue to feature predominantly the stories at Degrassi itself, not just follow the lives of the characters who have left Degrassi...
The special peisodes, if they happen, are not planned to be an ending... we are hoping hte series continues into Season 9 and beyond!
Here's some tentative episode titles:
801 Uptown Girl--Part 1
802 Uptown Girl--Part 2
803 Fight The Power
804 Didn't We Almost Have It All
805 Man With Two Hearts
806 With Or Without You

this show never ends
Guess Hilary Duff wasn't into that whole 90210 thing after all.
Although the actress/singer had been approached to join the show's growing cast, a spokesperson for the project confirms that Shenae Grimes of Degrassi: The Next Generation has nabbed the role allegedly earmarked for Duff.
Grimes will play [Brenda Walsh] Annie Mills, a theater-loving teen who relocates to Beverly Hills from Kansas with her adoptive bro and their parents one of whom will be played by Lori Loughlin.

So I guess her character Darcy won't be returning next season since she's been casted on the new Beverly Hill 90210 spinoff
