It doesn't look like the Master Chief will be going into retirement any time soon, as Microsoft has just registered domains for Halo 7, Halo 8 and Halo 9 (first spotted by Fusible). 343 Industries already made it clear that we'll see Halo up through a sixth installment, thanks to the reveal of the "Reclaimer Trilogy" back at E3 2011, but there's a good chance we'll see yet another trilogy in another 10 years.
Crazy to think, I know, but it makes sense for Microsoft to secure these domains, even if we're many, many years from these titles. The Halo franchise is Microsoft's bread and butter, so anyone who thought they'd simply stop after number six is clearly delusional.
What do you think? Will Halo still be relevant when it reaches its ninth installment? After all, the Final Fantasy franchise lost relevancy years ago, but that hasn't stopped Square from pumping out new installments.
