This is a quote from the ign story.
“What the guys did when they were working on Forza Motorsport 5, and I think this was absolutely the right decision, is that they rebuilt every single car for next gen,” confirms Fulton. “That was a must. That had to happen.”
"We benefit from that. You’ll see some of those cars coming over into Forza Horizon 2 but what’s great is that we’re also bringing new cars to the Forza franchise. Cars which really fit with the game.
“So obviously the [Lamborghini] Huracán is the prominent example of that; it’s the year’s hottest car. It’s great to have it on the cover. We also have a real variety of new-to-Forza cars across the game that really reflect the things you’re going to be doing in Horizon that you couldn’t in Motorsport. So some crazy off-roaders; some real serious off-road beasts.”
I’m assuming the cars from forza 5 will go to forza horizon 2 and then there’s probably gonna be 50 or 100 new cars to forza.
The first Horizon had a few race cars, that weren’t really street legal, Ferrari FXX and that 599XX and 599XX Evo, ect. So it would be interesting to see what really does cross over.
I’m going with the trend, and opting for the 200-250 theory. It sounds like pretty much the same PR routine has FM5, so I’m not getting my hopes up for much more than that.
