Thoughts on povetkin?

After hearing many good things about him on various forums(excellent amateur career, olympic gold medalist), I looked up some of his fights on youtube, and he seems to have a good mix of power, speed, and effective body punching. Has anyone been following his career for a while, do you think he's a serious prospect? Can he be a future unified champion? He's fighting Monte barrett on June 30th IIRC, and that could be an interesting fight for povetkin.
