They can keep the data on the cloud, yet we already seen that on Forza 5 and Horizon 2

Sadly for the rest of people who want to try something new, A.K.A another potential market. at least if they want to improve their gaming divisions.

I dont mind actually if they want to have another Forza every month, but as a gamer i am care for new "worth and great new IP". at least they can give some gap if they want to make sequel.

And as I explained, if Forza didn't exist some new game wouldn't pop up in its place.

I don't understand what the problem is, the Xbox One is getting new IPs in the near future as well as some reboots of beloved ones like Banjo, Phantom Dust and most recently Killer Instinct. Forza is not taking the spot or money from a different game. This team was hired to do one thing, bring a good racing sim to the Xbox 360/Xbox One. That is what they are doing. When it comes to new IPs, MS has other people on that.

all of their IP is over shadowed by "Forza "

How? If anything their IPs are overshadowed by Halo because of how mainstream the series was. Forza is simply icing on the cake to what is usually a pretty solid Fall line-up.

There is no problem for the avid and  loyal fans, i just give some suggestion, that the fact their console " image" is turn into FPS console box and Forza series consoles. They can bring Forza games but at least they can wait , so people will not think the game is rushed like Forza 5.

It feels like too much Forza at this point...

This is from a non Forza player btw...

They shouldnt of anounced this yet... IMO

But it's two different dev teams working on them from my understanding. One team makes Horizon and one makes Motorsport. That way both teams have about 2 years to make their next title.

Not even remotely.  Microsoft has also done a fantastic job of introducing new AAA ip and arcade along with bringing staple franchises this generation.  Whether you want a fighting game Killer Instinct, an open world game like Sunset Overdrive or Crackdown, a shooter like Halo or titanfall, a cinematic experience like TOmb Raider, a JRPG like Phantom Dust, a Japanese game like Scalebound, a tps like Gears, a platformer such as Max, Ori, and possibly Banjo,  a sim racer like Forza Motorsport, or an arcade like Forza Horizon, a zombie game lik Dead Rising, a sim lik Zoo Tycoon, etc etc.  This list goes on.  One thing is for certain, MSFT has been bringing new IP, rebooting games, and building on staple franchises since XBO has came out.

And plenty of these games have and wil sell a million+.  That isnt being overshadowed, but do realize Forza is a staple franchise
