Lots of rumors flying around....

I'm still waiting for World of Speed, but I would play Forza Horizon 2 if it hit PC.

I love the Forza series, so this is great news to me.  Hopefully they might port over the Forza Motorsport series as well.

The main Forza Motorsports series is a sim based racer like Gran Turismo.  This spinoff (Horizon) is much more an arcade style racer with the Forza feel.  I enjoyed Forza Horizon on the 360 and wanted a sequel.  But when I read that the 360 and Xone versions were different, and all the focus was going into the Xone version, I decided not to get it (don't have a Xone).  But if they bring over the Xone version to the PC, I will most definitely get it.

@Manbearpig
ok, thanks for the clarification.
With the exception of a few games I played on my friends PS3 at his place, I am completely out of the loop on consoles and racing games, last one I played I think was over 10 years ago, Midnight Club or something, a game a friend had.  Last console I owned was my SNES lol, so I can safely say, I'm a tad out of touch with that side of things. 
Hoping we get some of those titles, and not have them mutilated for PC, heard so many things about them, sound like they'd be fun.
