The move is not one of desperation. While The Orange Box has done well on consoles, with well over a million copies sold between the Xbox 360 and PS3 versions, Valve's Doug Lombardi characterized the PC release as "significantly stronger," citing a two-digit percentage increase over the console editions.
No official prices have been announced for the individual packages.
I saw those listed on "EBGames 'upcoming' list." I wonder if the Orange Box will stay on the shelf next to them, or if that options will go away at retail once the other's show up.
