Microsoft has flashed a slight glimpse at Halo 5's potential logo while they were showing off some of Microsoft's new technology on news network.
The image comes from a feature on UK television station Channel 4, where Microsoft were showing off some advanced technology in the "Microsoft Home". The image clearly shows the words "Inside Halo 5", while also showing "Project Gotham Racing", a franchise which has been defunct since Bizarre left Microsoft Game Studios.
It could have just been done to highlight the futuristic nature of the technology, as there's obviously no numbered Halo 4 in existence yet. However, it shows that they intend to at least go that far with the series.
