Other key titles that can't come out fast enough:

Arrested Development: Season 3
Slither
Blade Runner: Final Cut
24: Season 5

Here's My Top 5:
Maltese Falcon 3-Disc Special Edition
Seven Samurai: Criterion Collection 3-Disc Edition
Lady Vengeance Tartan R1 Edition
Lost: Season 2
Robin Hood: Men in Tights (Single Disc release)

Honorable mention goes to the Brazil 1-Disc CC, The Green Mile SE, L.A. Confidential Multi-Disc SE, the Blade Runner Multi-Disc set, and the Superman: The Movie 4-Disc SE.

Only one:

Animated Star Trek: The Complete Series

#1 is robin hood: men in tights! #2 is probably the wizard. also the superman set that everyone is excited about and brazil probably. want to get some of the tv shows i grew up with too on dvd.

Superman Returns HD DVD
King Kong Extended Edition Gift Set and/or HD DVD
Smallville Season 5
Mission Impossible Trilogy HD DVD
2001 HD DVD
The Thing HD DVD
Batman Begins HD DVD

basically most of the titles from the "Look and Sound of Perfect" website.

An Evening With Kevin Smith 2: Evening Harder
Clerks II
Slither

I take it we should mention only the ones that are currently slated for release (otherwise, my list would be MUCH longer).

- Double Indemnity
- Godzilla/Gojira Deluxe Collector's Edition
- Astaire & Rogers Collection, Vol. 2
- This Island Earth (maybe, depending on special features)
- Film Noir: The Dark Side of Hollywood set
- Maltese Falcon (3-disc special edition)
- Forbidden Planet
- Pretty Poison

At this point, there aren't too many for me. I should be getting into HD-DVD soon. I will have plenty of titles to buy in that format, but for DVD it's mostly some TV shows (AD, Lost) and less popular movies that may not make it to an HD format for a long time (RH:MIT for example).

Even if movies like 2001 and Grease don't get HD-DVD versions when the DVD SEs are released, I know they're coming at some point. I'll wait.

King Kong extended edition
Blade Runner
and some of the UE bond films (depending on the V/A quality and if they ever come out in the states.)

Sesame Street Old school Volume 1
Miami Vice
Family guy volume 4
Simpsons season 8

The Wizard, Finally getting a dvd release.

I'm really really anticipating Region 4 releases of A History of Violence (as yet unannounced), Kingdom of Heaven 4-disc DC (Stptember 6th for us), and Superman Returns (most likely sometime close to christmas). Other than that, on my "to buy" list are Fight Club, Citizen Kane, Taxi Driver, Match Point (16th August) and Dave Chapelle's Block party (17th August)

I'm looking forward to getting Sergeant York as a gift for my husband. He really liked that movie, & he doesn't normally like classic movies.

For myself I'm looking forward to the new releases from Jari Love this fall, Ripped 1000 and Get Ripped & Chiseled. I'll also probably order, though its been available for a while & doesn't really qualify as a new release even though its new to me, the Wizard of Oz 3 disc set.
