We've been tentatively calling the Xbox One version of Gears of War the Gears of War: Remastered Edition. We don't know for sure if it's a remaster or a remake or exactly what it's going to contain, but these could all be cleared up if it's actually going to be called the Gears of War: Ultimate Edition.
According to Gematsu the long-rumored remastered edition of Gears of War could be called the Gears of War Ultimate Edition. Why? Because that's what's been rated by the Brazilian ratings board. The “producer” is Microsoft and it's listed on the Brazilian Government's website as scheduled for a 2015 release. It's not an official indication that the game is actually coming, but it definitely makes it hard to deny it at this point.
When pressed for a response on the issue, Xbox head honcho Phil Spencer deferred to a diplomatic stance about waiting for E3, mentioning on Twitter...
Later down in the thread someone asks if Microsoft will space out their big announcements between E3 and GamesCom this year. According to Spencer, they will.
Phil Spencer had mentioned previously that Microsoft would be holding a press conference this year at GamesCom as well. However, this also calls into question whether or not Microsoft will have a proper amount of content to fill out both shows? While Gears of War: The Ultimate Edition will likely take up some time at E3 it is just a remastered edition at the end of the day so there's a lot of curiosity floating around about how much Microsoft will show off that they're going to need to hold two conferences, one at GamesCom and at E3?
As far as what we can expect from Gears of War, some have claimed that it was just a remake of the very first game being upscaled to 1080p and 60fps for the Xbox One. Others have claimed that the package will contain a bundle of the first three Gears of War games from the Xbox 360 and that the package will be similar to what 343 Industries and Microsoft did with Halo: The Master Chief Collection for the Xbox One. If they do indeed plan on rolling out a bundle package I'm sure it'll go over a lot better than a basic remake of just the first Gears of War.
Of course, there's also going to be that looming cloud over Microsoft's head regarding Halo: The Master Chief Collection and the multiplayer problems players experienced with that bundle. There will definitely be questions as to whether or not Microsoft and the studio in charge of the remake can deliver Gears of War: The Ultimate Edition with the multiplayer properly intact.
