Speak for yourself, Halo 2 Anniversary and Forza Horizon 2 releasing this year are megatons for me and I'm sure it is for a lot of other Forza and Halo fans.
About Halo 5 coming next year, its not really a big deal since the Xbox One is getting some really interesting exclusives this year. And more development time isn't a bad thing either so i don't really see why it should be a big thing.
Controlled leak or not, it sure got a lot of people hyped which is a positive thing.
So getting an old old port of a game you already can get is megaton but getting your absolute new game from same franchise delayed a year is not a "big deal" .. Ok bro.
I never said it wasn't a positive leak. hell, that is exactly why I think it was a plant . It was aimed at grass root xbox fan and that is why it made perfect sense to do it in GAF where that audience is.
Again, it really created that positive vibe without really giving out any info about games themself instead of target dates that can change anytime.
