The UK retailer Tesco has added something called ‘Upcoming Halo’ to their website.
You can view the page here before it is pulled down.
Many assume instantly it may be Halo 2 Anniversary, or the recently rumoured Halo 3 PC after it showed up in Steam’s database. An announcement of a Halo game at E3 2013 all but makes sense if Halo is to be a launch title of the next-gen Xbox which is also expected to launch in 2013.
Although there is no information on the website, it is safe to assume that a new Halo game will be coming in 2013, and we should expect to hear about it very soon!
