While true, the same happened with SM3DW. But I'm not betting on it.
Zelda U will NOT be a 2015 title.
They are releasing Hyrule (Nintendo will handle the promotion and distribution for the West) this year. Plus, they still have to release various games already announced. Plus, they struggle with HD development (Namco even helped out with MK8...!!!), plus c'mon the Wii U it's been out on the market for 16 months, we should know how Nintendo in handling it.
That said, there could be an unannounced game releasing in late 14, but it will not be Zelda.
