It will be up probably, as all the games already in Japan hit the west. But I'm not that optimistic, that it can manage 20M. That's quite a growth, if it does that I'm really impressed. More something like 15M.
Pokemon will not have the big impact. If gen 6 is coming (big if) it will be late 2013 at best. So it will have effect on sales mostly in 2014.
