Hi I 'm using google translator
I have a question It is possible that 343 Perform a remake of Halo reach? or that would be a bad idea?
Greetings from Mexico! 
Possible? Yes. Probable? Well, that’s a different question altogether, and no one really knows. More than likely they won’t, since they are finishing Halo 5, and Reach is supposedly on the initial release of BC coming out in November.
Reach is most likely getting backwards-compatibility on the Xbox One this winter. We’ll have to wait and see.
