Apple is now accepting orders for DVD Studio Pro 1.5 and Cinema Tools 1.0:
DVD Studio Pro is a software application from Apple that makes it affordable and simple for non-specialists to encode, author, and write professional-quality DVD-Video discs on their Power Mac G4 desktops. If you're shooting and editing using digital video, you can now retain digital quality and precision all the way to the final product.
Cinema Tools provides functionality to Final Cut Pro to edit film digitally and work with the emerging 24P high-definition video standard. No other single application or suite of products of comparable cost can match the ability of Final Cut Pro and Cinema Tools to work with all major formats from OfflineRT, DV, SD uncompressed to HD, as well as now finish on film.
These products have not been officially announced... though are expected to be announced at NAB
Cinema Tools appears to be fruits from the acquisition of FilmLogic last year.
Update: Apple officially announced these products today.
