From Geneon, which only holds the license for these films for Japan so it probably doesn't mean any of these will be coming to the US at around the same time. All discs shown in the link will be released Dec. 5.
No specs/extras announced yet. Terminator 2 Premium Edition will have both the special edition and the theatrical cut on separate discs, and the special edition will also be available separately. This will probably be a new BD-optimized encode and will look at least a little better than the UK release.
Sky Captain and Aeon Flux are also coming, I imagine they will look better than the old Paramount releases and will have lossless audio.
