The snoops over at NeoGAF have uncovered multiple old and new signs that Giant Squid's Abzû is heading to Xbox One. This includes a post on GameStop, a filing with ESRB, and a post on GameFly (which appears to no longer be current). The listings also point to a retail release in November.
It may very well be that Abzû is a timed exclusive and there really shouldn't be anything preventing publisher 505 Games from releasing it on Xbox One.
We quite enjoyed the tranquil adventure and you can read up on our thoughts in the review.
