Disappointing to see the lack of luigi's Mansion and Castlevania from this list. I thinks that they were probably pushed back because they aren't sure fires to sell considering how packed this. They aren't as a big as mario 3d land and mario kart from last year.
Paper Mario on the other whilst in the same boat has been in the works for much longer. It was one of the games that were said to be coming when the 3DS was anounced. It is most likely finished and as polished as can be by now so Nintendo would be less willing to sit on it then luigi's manison because of that.
Thank goodness, that paper mario is the game that I was most looking forward to of the 3 big hitters named above.
