There are currently 12 studios. If they acquiire 3 more than it's 15.
At a 4 exclusives per year every in a time span of every 3-4 years.
hm... I'm getting off-topic now and may move this later, but if we put that into a line-up list to get some context of where their studios stand in terms of game dev timeline:
(including non-MS studios and non-MS published):
2017
- inXile Entertainment - Torment: Tides of Numenera
- inXile Entertainment - The Mage's Tale
- Ninja Theory - Hellblade (ported to Xbox 2018)
- Turn 10 - Forza Motorboat 7
2018
- Compulsion Games - We Happy Few
- inXile Entertainment - Bard's Tale IV
- Obsidian Entertainment - Pillars of Eternity 2
- Playground Games - Forza Horizon 4
- Undad Labs - State of Decay 2
2019
- Coalition - Gears of War 5
- DLaLa Studios/Rare - Battletoads
- inXile Entertainment - Wasteland 3
- Ninja Theory - Star Wars VR
- Obsidian Entertainment - The Outer Worlds
- Splash Damage - Gears Tactics
- Splash Damage + Ruffian- MCC PC + MCC Xbox Reach
2020 pre-launch
- Coalition - Gears 5 post-launch content
- Obsidian Entertainment - The Outer Worlds post-launch content ?
2020 holiday launch
- Ninja Theory - Hellblade Team launch title? ~2.5 years
- Rare/Iron Galaxy - Killer Instinct Next - launch title ?
- Relic Entertainment - Age of Empires IV launch title?
- Turn 10 - Forza Motorboats, coats, goats, and float16 - launch title?
I'm almost hesitant to put Halo as a launch title so that it doesn't overshadow other stuff where traditionally launch is the best time to put forth new IP because consumers are facing a drought.
2021 (guesses, of course)
- Coalition - Year 2 Gears 5 content, a waning of "MS Shootbang" to be followed up by the other McShooty Shootbang from 343i.
- Iron Galaxy - Killer Instinct Next Season 2
- 343i - Halo Infinite? Maybe too strong of a game for 2020 launch...
- Compulsion Games - post-We Happy Few game? - 3 years
- inXile - smaller title - I have no idea what to make of their studio given the number of games they have released since 2017
- Obsidian Entertainment - from the PoE team ? ~3 years
- Playground Games - Fabble rabble
- Turn 10 - Forza Motorhats content
- Undead Labs - Post-State of Decay 2 ? - 3 years
2022 (guesses, of course)
- inXile - bigger title from the Wasteland 3 team ? ~3 years
- Iron Galaxy - Killer Instinct Next Season 3
- Ninja Theory - from the Star Wars VR folks? ~3 years
- Playground Games - Forza Horizon with less mundane game mechanics.
2023 (guesses, of course)
(incomplete) Gotta run for now
---------------------------------
So Iron Galaxy is apparently ~130 people. I wonder if they'd be in the running for acquisition. Their 2018 title, Extinction, didn't seem to make any waves. They have otherwise done some Switch ports.
Maybe MS will pull a Cuphead Switch on more of their smaller catalogue titles,
"Perfect for Switch" (and POW Switch/Lite Switch)
. Battletoads comes to mind, although we haven't seen anything yet about what that is.

Oof... Well, we know Motorsport is skipping 2019, which probably means 2020 launch.
PG's rumoured Fable game could be hot on the trail, but who knows. I was guessing that the next Forza Horizon would take place in Japan (accidentally coincide with the Olympics in 2020), but... maybe the next FM will do something smart like that as a build-up instead. IMO, FH could use a break to go back to the drawing board and to give them more time to produce something less boring.
