It's a fun article. I'm gonna go point by point on this one...
1. Fable at Rare COULD happen eventually, but it would require Sea of Thieves to wrap up, and for a creative director over there to both want to make Fable and for Microsoft to agree to whatever pitch comes out of that desire to make it. I'd rank that one as very unlikely.
2. I don't know enough about this one... Shadowrun sounds like a pretty inconsequential IP for them though. And making a shooter RPG is very expensive. I don't think this would be viable, but like I said, I don't know much about it.
3. Could happen, and could be a mid-tier game, assuming Splash Damage has staff available shortly.
4. This will not happen unless Microsoft has money to burn. It would be another niche game that wouldn't move units, and would be very expensive to produce. I'd say this is basically ipossible.
5. Sure! Could be another cheap mid-tier game that might, alongside GREAT new Halo and Gears games, might help turn the console's perspective around. Depends on interest from those involved, but I could see it... but probably not using the NInja Gaiden IP. Maybe a spiritual successor of sorts?
6. No. As much as I'd love a new Splinter Cell, I think it will indeed happen, but Ubisoft will want it to be far bigger than it's been, and an exclusive partnership would not be seen as a great move to help the franchise's growth. Ubi is too big. This would be too expensive. Just doesn't make any sense.
7. I don't really see why rebranding indies as XBLA would do anything, but sure. I also strongly disagree with the narrative that Xbox Live is still a major competitive advantage over PSN. PSN is likely quite a bit bigger than XBL at this point.
