If this is true, it could be very cool! 
I would take this with a pinch of salt. 343 haven’t said anything official about this, so its probably just a bundle that gamestop themselves are doing. It possibly just both games shipped together in their own respective cases, not a single case with the boxart shown in the listing.
Until 343 officially says anything on this, its best just to assume its what I said.
Seems legit only because Gamestop usually only lists titles that are definitely going to get released. The release date seems a bit suspect though. I think the origins bundle is happening but the date is probably tentative pending an official announcement 343/Microsoft. This would be a big plus for me though as it might mean that more people will play reach!
Sounds stupid to me, yeah its real but stupid.
Seems like since Bungie left, Microsoft have just milked Halo.
( My view on things )
I love the idea of more people playing reach and enjoying where Bungie’s Halo games started and ended. I wholeheartedly agree however that Microsoft is now shamelessly milking Halo. Isn’t that why they created 343 industries? I think they should have just left master chief drift off into space and leave his fate a mystery. Now Microsoft is expanding the reclaimer trilogy into the reclaimer saga and then there’s spartan assault… Expect to see the halo utter milked dry next-gen.
