A new version of "Batman: Arkham Knight" may be coming soon, and it could feature all of the title's available downloadable content.

Recently, a listing for a game known as "Batman: Arkham Knight Sonder Edition" appeared on the German version of Amazon.

According to the listing, the "Sonder Edition" will be released for the PlayStation 4 (PS4) and the Xbox One, and it is already set to come out on March 17.

It's unclear what the "Sonder Edition" of "Batman: Arkham Knight" would actually be, but there's a belief that it may basically equate to a complete version of the game.

According to Design and Trend, it would also make sense if a complete version of "Batman: Arkham Knight" that included all the available DLC would be released soon.

As the website pointed out, the last significant content drop for the game was already released in January, and if the game's developers truly have no additional plans to introduce anything new, then now would be the perfect time to launch a "Complete Edition" of "Batman: Arkham Knight."

It's also common practice for developers to release more complete or "Game of the Year" editions of popular titles so the possibility that one could also be released for "Batman: Arkham Knight" is at least somewhat likely.

Interestingly enough, the listing spotted on Amazon Germany indicated that the upcoming release would be made available for PS4 and also Xbox One but made no mention of PC.

The current version of "Batman: Arkham Knight" is available for the PS4, Xbox One, and the PC, although it does not perform similarly on all three platforms.

The PC port of "Batman: Arkham Knight" has been problematic right from day one, and the issues were so serious that Warner Bros. even offered full refunds for it no matter how much progress owners had already made, BBC reported.

It will be interesting to see if a "Complete Edition" of "Batman: Arkham Knight" will be made available for all three platforms should one ever be released.
