Over on the Adventure Gamers forums, Stain has posted that there is a new line of LucasArts reissues being sold under the Lucas Classic Line banner. These include many of the old adventures that have long been out of print, including The Dig, Full Throttle, Sam & Max Hit The Road, Day of the Tentacle, Grim Fandango, Monkey Islands 3 & 4.
No official word yet, but one would expect the games to ship with an XP compatible launcher.
