Its like saying black and white is the new color, movies like sin city or anything succesful in black and white isnt a trend. NSMB is made 2d because its like a remake, sonic isnt even good nowadays and little big planet is 2.5d.
Games in DS and PSP are cheaper and easier to make in 2D(on consoles as well but people expect 3d in their consoles given that they are more "powerful").
So, I see it like an artistic thing, maybe pushed by some facts like nostalgia or smaller developers trying to create something smaller but creative and artistically good because of lack of funds. Thats why I think 2d wont start replacing 3d and 3d will still be expected from most big developers in the future, as in better graphics too.
