Can we just go with 'Improved Bradley'?
That thing is a frickin' beast....
Honestly if the Canada had Bradley, then go Bradley A4 with the Hellfire and Javelin modifications done to it, I would say up-gun the cannon to 30-35mm and call it a day.
But Canada does not - so there is a clean sheet of paper, which I honestly think is a good thing (as long as it doesn't have wheels)
I am a CV-90 fan as well, but I think it's design is also a little long in the tooth, as while power packs have been upgraded in both, the demands of the current and future vehicles for power, cooling and data are not something ever considered in anything over 5 years old.
The four most advanced companies in this: GDLS, KNDS, RM, BAE (in no particular order).
BAE is the only one without a publicly disclosed next Gen Tank, as well BAE also hasn't publicly debuted their early XM-30 model since pulling out of the program (the company walked away when the cannon was changed to 50-65mm, although they did not disclose a reason for leaving).
*so maybe I did put BAE at the last subconsciously for that reason?
Personally I think a 35-40mm cannon is the best bet - and lean heavily to the 40mm CTA cannon from the Warrior Upgrade (that the UK cancelled). It offers a substantial payload (compared to the 25mm Bushmaster on the Bradley and LAV), has great velocity, the cannon is reliable and the ammo stores very easily (as someone who dreaded loading the belts from the M242, the 40mm belts are not a snag hazard and don't want to grab fingers, thumbs or pieces of your uniform). Ukraine has shown what the 25mm APFSDS-DU round can do to Russian tanks - and a 40mm round in that would have significantly better performance, even better than the GAU-8 on the A-10.
Ideally I want 4 Crew - Driver, Gunner, CC, UAS/SA/Radio guy, where a Dismount Commander can also have clear SA and access to all vehicle sensors and inputs.
