No, I think 2006 for Nintendo was an unrepeatable year. A console redesign, a new 2D Super Mario entry after something like 14-13 years, Mario Kart DS just released a couple of months before in 2005, the "casual" market explosion with Brain Age (even my mother got a DS that year), Nintendogs was still showing legs.
2013 will be a very strong year, (the Pokemon + Monster Hunter combination is just huge) but I doubt it will beat 2006.
