While rumors of another Vacation movie being developed is hardly new, it seems the rumor is actually real. According to Variety, New Line is getting ready to follow a new generation of the Griswold family on an adventure.  To make it happen, the studio has hired screenwriters Jonathan Goldstein and John Francis Daley (Sam Weir from Freaks and Geeks!) to pen the update.  David Dobkin's (Wedding Crashers) is going to produce.  For more on where the Griswold's will go, hit the jump:

According to Variety:

Story will focus on Rusty Griswold, now a grown man, who decides to take his own wife and kids on a road trip to Wally World before it closes forever. Chase is expected to reprise his role as Clark Griswold, now a grandfather.

They also claim the movie will be closer in tone to Planes, Trains and Automobiles than the previous chapters.

I gotta say...I like the way this is sounding.  Instead of trying to make a bad situation comedy, the story sounds like it could work and they've found a way to get Chevy Chase involved, but not as the main character.  Also, what's great about the first film is how director Harold Ramis took the normal family vacation and spun it into an out of control adventure.  It sounds like the new one is following that same path.

What isn't known is who will play Rusty.  Because if you've seen Vacation (1983), European Vacation (1985), Christmas Vacation (1989), and Vegas Vacation (1997), you know Rusty and his sister Audrey were always played by different actors...which was always kind of funny.

Saying that, in the first Vacation, Rusty was played by Anthony Michael Hall.  It would be very cool if he was cast as Rusty in the sequel as that would mean he'd play the same character almost 30 years later!

Finally, Vacation is the fourth project at New Line in 2 1/2 years for Jonathan Goldstein and John Francis Daley.  Clearly the studio likes their writing as they've also been working on Horrible Bosses, Burt Wonderstone, and The $40,000 Man.  Seth Gordon (King of Kong) is attached to Horrible Bosses and it's about three friends who resolve to kill their employers.

While I haven't read those other scripts, you don't keep getting work without talent, so let's hope they craft a great adventure because I'd love a new Vacation.  More as we get it.
