“I think you may be ahead of yourself on Halo 5,” Downes said. “I wouldn’t expect anything until 2015. What you can look forward to this year is an anniversary edition of Halo 2.”
Yes, that indeed says that Halo 5 will not make a 2014 release as many had hoped. However, this is now the second source to reveal that Halo 2 Anniversary is a thing and is probably coming out at the end of 2014. The first source being a massive and mysterious info dump on NeoGAF.
The stars are aligned for this to happen, however, as 2014 marks the 10-year anniversary since the original release of Halo 2.
