I beg to differ. When the US Army cooked up early land warrior working prototypes back in the 1990s they were basicly wearing a computer tower in a pack frame that tipped the scale at 40+ pounds. Today almost every feature is found in a commercial smartphone technologies available off the shelf. The only parts that still lag are individual fused sensors but even that's making leaps. The US Army is already issuing fused sensor night vision to troops. The all in one mode I think has been proven to be the primary failing by breaking up the individual components and focusing on there miniaturization and battery life extension, factoring in commercial trends and development the issues become less severe.
Lithium Ion batteries are getting better every year true for a smart devise its not as long lived as the battery life on a Comp4 Aimpoint red dot (something like a year of continuous use) but we are starting to push the power spans longer and longer add in external adaptors and individual alternative power supplies like solar blankets. The more mobile orientation of mechanized combat and its becoming more and more a practical system.
already in both Iraq and Afghanistan the US Employed digitized command systems down to the squad level. Using smart devices on a Secured G3 network.
in Africa French troops are already deploying Felin digital suites.
and not only the digital goodies either land warrior in the US also included FR environmentally suited clothing IE combat shirts and pants designed to resist fire and allow optimized movements through the battlefield. This is another area the PLA seems lacking in.
as to the OICW the Dual gun is in my opinion not practical. To big to wield, to heavy to carry even with a exoskeleton. Breaking them up and going into standalone systems makes the most sense. Already the American M25 "Punisher" has proven a effective system in Afghanistan. The South African Neopup is also proof that a stand alone weapon can work. Although it means packing two individual weapons the smart grenade launcher and a personal weapon. Its easier to use and employ. As well as effective.
It's always the power source that matters, because in a military ops there's very little time for those digital gadgets to be on stand-by mode, they've to be on all the time. The technologies might be here today but they need to be practical enough to survive beyond R&D labs and into real world, and more important than not, economical to produce...unless we got World War 3 or alien invaders to fight, budgetary committee is the worst enemy of all.
Integrated HUD is feasible, if and when a hardened, military grade version of the Google Glass is realised, then all that is need is to integrate inputs from various sensors (weapon sights and stuff) into a unit not bigger than an iPhone or whatever.
As for China in this thing, well let's just say they've got too many stuff on the to-do list and not enough smackers to tackle everything at once. Since it's hard to imagine them giving up in this field, they might put this on the low priority for now, small-scale compartmentalised researches running at various labs and institutes.
