I'd say it would be more likely that armored exoskeletons would appear - at least as proof of concept models - a great deal sooner than that. The power systems to make them feasible for long term field deployment could also be far closer than you might think. They can already produce exoskeletons capable of assisting a soldier carrying a heavy pack and full kit (as well as its own weight) so an exoskeleton that caries an articulated armor as well probably isn't all that far off.
