With Sony and Microsoft releasing the PS4 and XBoxone with games like Assassins Creed 4,Battlefield 4,WAtch Dogs etc it shall be interesting to see if Nintendos big games this fall can maybe push sales for their console. I mean Mario and Donkey Kong have been massive sellers for them in the past and there's also the likes of Sonic as well.
Handheld wise Nintendo should sweep all before them with Zelda A Link Between Worlds and Yoshi both coming out. The Vita has had virtually nothing coming out for it and the system looks finished from the looks of things.
It shall be an interesting end to the year will Nintendo pick up the pace thanks to their 1st party titles or will either the PS4 or XBoxone steal the holiday season.
