As of now there are no longer any technological constraints preventing the 2029 or 2035 parade be made up of humanoid combat droids formations followed by large walking battle mechs and PLA troops in power armor, of course in practice we're more likely to see quadrupeds, maybe large hybrid electric ones with cannons, which would still be cool.
Personally I think the first true power armour deployment in the real world will be in the form of power armoured troops riding quadruped mounts.
Currently the key limiting factor for true power armour is in making a power source compact enough. The mount side steps that issue by allowing you to use the mount to carry the primary power source, with the power armour itself only needing a secondary power source that only needs to last for a few hours instead of days or weeks.
The mounts also solves the speed problem with power armour, as slow prodding suits will get absolutely obliterated by ATGMs and FPVs.
But sadly, in the world of FPVs, power armour might become obsolete before its even developed, as no level of protecting such power could realistically provide would be enough to protect against FPVs with shaped charge warheads.
Probably quieter and more terrain flexibility to go with quadrupeds. Might also be more agile though not sure if that will matter so much.What is the benefit of using fancy new robo-horses instead of regular old vehicles? IFVs, APCs, or even ATVs if you want individual transportation. Why does power armour need quadrupeds instead of wheels or tracks? Sounds like a solution in search of a problem.
On a lighter note, I found this Pakistani podcast on the parade. Don't take it too seriously, but they are obviously window shopping.

A multitude of reasons.
Putting a bunch of power armoured troops into one vehicle just makes that one vehicle a massive priority target for opfor. That holds true even after your troops dismount since that vehicle is also their primary power source, so taking that out drastically reduces your power armours field endurance.
With the power source limitation in mind, putting your primary power source in vehicles means your troops need to regularly return to said vehicle and sit in the crew bays and recharge, so you need to either put your vehicles closer to the contact line, thereby increasing the risks to said vehicles, or have your power armoured troops spend a significant proportion of their time ferrying back and forth. With mounts, they can do 90% of combat ops mounted, including combat engagements, and only dismount for specific tasks like clearing small buildings. With mounts, you can also bring spares for redundancy, and depending on how much you want to spend on the mounts, those could easily be combat UAGVs in their own rights, just like a much bigger, more advanced robot dog, so your section could easily dismount and basically double its effective combatants.
You can make the mounts wheeled or tracked, but that won’t provide the versatility of legs, especially in complex terrain such as forests and shell pocked roads and bombed out buildings and minefields etc. Even in urban combat legs holds a significant advantage over other forms of locomotion since cities are designed for legs.
I could go on, but I think you get the point.
