Well yeah. One of the new units is an armored grizzly bear... which you apparently deploy by parachuting them into battle. I don't think they're going for a hard-edged gritty depiction of a world that almost was.
But yeah, that looks exactly like CnC3, which looked like RA2, which looked like CnC2, etc. Naval combat has always been a throw-away feature many RTSs, so maybe if they do naval battles right then RA3 might be a big refreshing change to the franchise. Otherwise, it's yet-another-installment.
