Universal want to release a new 'Dogma' set next year, reinserting a few of the deleted scenes AND they want to give Smith the money to finish a few that require SFX. It's pretty interesting though, 'Mallrats' only came about because the title was withdrawn and when Smith asked why, they told him it was because they were going to re-issue a lot of their best-selling titles, and 'Mallrats' was among them. They also made it clear that they were going to release the set with or without his help. They've also said the same thing about 'Dogma' - It's up to him if he wants to participate, but they're going to release it regardless...
He also said that 'An Evening with Kevin Smith 2' is being held back until next year now because the company making the DVD insist on holding out until 'Clerks 2' is released.
He talks about all of this on his interview over at www.dvdtalk.com
