Well it's official that NHL franchise won't instantly be launched on next-gen. The games that will be upon their release dates unique to each franchise, Fifa, Madden, UFC and NBA. This is according to EA Sports themselves at the XBOX ONE Reveal.
It also hurts that the XBOX ONE will NOT be backwards compatible.

So us die hard NHL fans will have to hold onto the 360 for a while before you'd even see NHL 14 get ported over (Which obviously wouldn't have any direct level of enhancement for the next-gen. Just the same game graphically and engine wise as XBOX360 version)
