Intrigue's afoot in Germany, where the local ratings board has a listing for Prince of Persia Classic on Xbox 360.
The Unterhaltungssoftware Selbstkontrolle site shows the game as an action-adventure and the publisher as Ubisoft, as you might expect.
While little else is known about it, the addition of "Classic" in the title and the fact it's only listed on Xbox 360 has led to speculation that we may be looking at an Xbox Live Arcade revamp of one of the older games here.
Unfortunately, Ubisoft's UK representatives said they didn't know anything about the listing when we spoke to them this morning and were therefore unable to confirm or deny it.
Still, listings like these have proven to be a strong indication of upcoming titles in the past. So fingers crossed.
