They are most likely making a HALO 5 XBONE next year instead. If you wait, you can get that one and then pick up the Master Chief Collection cheap.
Plus, maybe you'll get Halo 5 free in the bundle or the Xbone may get a price drop by E3 2015. Point is, it's coming. I have Halo collector's Xbox 1, Halo 3 Xbox 360, and I noticed this trend long ago.
It is almost a given that a Halo 5 themed Xbox one console will be made. Every Halo game to date has had a Halo themed console to go with the game. Except for Halo Wars. It is unlikely that a Halo themed console will be created for the Master Chief collection. But for Halo 5 it is a given.
I would buy a Halo 5 Themed special edition console in a heartbeat. With 2 controllers and the Halo 5 pack in game. A larger HDD would be sweet.
@SolidTy: This is the most likely scenario. But dang such a long wait. :/
;) Yeah. Technically, it's an HD collection which usually don't get special consoles (actual sweet custom models) in years past, so it's probably not worth a full new Xbone, but yeah it would be nice for fans. Yes, I did see HD collections sold with consoles, but the consoles weren't sweet and cherry. Unlike the original Xbox Halo models, Halo 3 360, and Halo Reach 360.
