Gears 1-3 were created with 50 man team at Epic and tight budget.

Black Tusk has more than 100 people and a lot of them come from Epic. Additionally, MS Vancouver (predecessor of BT) already has a protoype of an adventure game called Shangheist.

For me, Halo 5, forza and TR are meh. Now QB seems something I want to know about.

What annoys me is that MS is so focused on the holiday period. Games like Halo should always be holiday releases, but spread out the exclusives through the year MS!

I'm sorry but I'm sure that after Gears 1 development was neither tight on budget nor only 50 people strong on the Gears series, just check Gears 3s credits. Also you're ignoring the natural increase in manpower that is needed for game development this gen, especially if they want to get the next Gears out in 2016, which I'm sure they will.

XB1 has the best games for 2015 and it's not even close. I still have exclusive games to finish from the holiday 2014. Then I picked up Ori and SOD, and KI keeps getting better, and I'm sure we will see KI season 3.

Also the rumored Joe Montana would be July or August. 

Rod Fergusson said their team was small and overworked.

Epic was not interested in Gears IP like MS was. They're mainly a game engine company.

If there's one thing that doesn't lack in MS studios, are devs with UE4 knowledge. Crackdown, Fable, Scalebound, etc... are all being made with UE4 engine. Epic also has a technological partnership with MS to provide and assist with UE.

Manpower won't be an issue in Gears of War production.

That still doesn't change that Gears 3s credits clearly show that the team was clearly larger than 50 people.

Also I don't know what you're trying to suggest here, but 100 people for an AAA game that is likely supposed to come out after only 2 years in development (makes me honestly doubt this can even be ready next holiday season) is ridiculously small in todays industry and that is not only because of the engine. Halo 4s dev team was 200 people strong in the end (+150 contractors) for example, I don't see how Black Tusk could currently have any resources for another project, considering what they are tasked to do. 

After the Phantom Dust cancellation, I can't trust Microsoft to do anything right regarding exclusives.

im down for more exclusives,just hope they're actually good o.o

Don't/Shouldn't release if they aren't ready.
