Hey guys,
    so I have only been on Steam for about a month and I am already in love.  I am planning on buying Fallout: New Vegas but I was trying to decide if I should go ahead and preorder now or wait until later?  I played through Fallout 3 on my roommate's PS3 but I don't have access to that anymore and I was thinking about buying that as well.  My question to the community is this: 
 
Should I wait to try to see if they do any sort of combo sale for both games or should I just bite the bullet and buy them individually now?  (That way I'd be able to play through Fallout 3 again leading up to Fallout: New Vegas & I'd also get the preorder items for New Vegas.)
 
I'm just curious about everyone's opinion as well as any insight you all might have if you've used Steam for a while.
 
Thanks!
