Probably not before April 1, 2015 (the end of the previous fiscal year and the beginning of the new one). A price cut now would just f**k up their fiscal year and cause them to post losses, so they will ride out the $299.99 Wii U until next year at least.
I think they'll shift to a $249.99 bundle come summer 2015 with Super Smash Bros. U + a starter Amiibo.
Nintendo doesn't bundle brand new games, they wait until the games sell their initial fill (to cover dev costs) and then the game gets bundled afterwards. Mario 3D World is just being bundled now for example, they will wait for a little with Smash.
Splatoon and Mario Maker IMO won't be bundled right away.
