was wondering if anyone came across any new gadgets at NAB for HDV camera such as frame store, P2, and anything cool for and of the more proffessional camera like Pani, JVC, or Canon XLHD1.

There was the eLipz accessory from Anton Bauer. It's a new battery that mounts underneath the camera inbetween the camera and tripod for a compact workflow. To further that, they've got the eGripz accessory which is two bendable handles that mount underneath the camera or eLipz for a Fig-Rig-esque handheld configuration and, because they're bendable, can allow for the camera to be held in a variety of ways. You can also have the eLipz and eGripz attached to the tripod so you don't have to remove them to use the tripod and vice versa.

Century Optics also had a series of new lens attachements for HDV-based cameras as well as the HVX200. Particularly wide-angle lens attachments.

16x9/Chrosziel/Formatt/Century, all of 'em, had new matteboxes for the HVX200 and HDV-cameras, only the XLH1 and JVCHD100U I think or they might not have had new ones at all for HDV =/.

Sony had nothing new, they just killed the HC1 and the FX1 wasn't on the show floor so that may be dead too. Sad =(.

Panasonic had some kickin' production LCD's, I don't think I saw the new 26" one, but the 17" one was a great companion to the HVX200 and I could see it being used for HDV productions as well. They also had a nice big 103" Plasma HDTV that you could watch all your new HDV footage on, price was TBA.

Apple plans to add support for HDV 24p solutions, JVC's 24p and Canon's 24F, in a future release (ie. 5.2).

Bogen Manfrotto was hyping the 519 tripod head this year for use with the bigger things like the XLH1 and 35mm adapter solutions.

The Firestore FS-100 was a big plus all around the different camera areas.

That's about all I can think of at the moment. I didn't notice anything too new in terms of support equipment or anything like that, since I don't know much beyond Bogen tripods. Most of the software was just the same or had minimal upgrades.
