James Wan is a popular man. After the Saw series he created a big hit out of Insidious and now he's currently working on "the Warren Files." With Insidious 2 on the chalk board Leigh Whannell is brought back on to pen the script.
Whannell said:

"I can say that yes, my character will be seen in Insidious 2.  It may probably bum a lot of people out, though, to hear this news. It's part of the reason I don't even read the internet message boards anymore; there was this hatred that spewed out from fans saying 'I hated those guys! They sucked! They ruined the movie!' so there will probably be a lot of people out there who will be disappointed to hear that the Specs and Tucker characters will be coming back."

There is no date on when Insidious 2 will start production but it is slated for a 2013 release.
