Cross your fingers that this FNAC record store in Spain knows what it's talking about. Via U2Valencia.com comes this photo of a sign listing upcoming albums and release dates, and U2 is included with "November 2013" as the date.
We don't know if this sign is showing in just one store, or in multiple FNAC stores. And we don't know where this store is getting its information. We do know that, as of this evening, there's no new U2 album listed on the FNAC.es website.
So for now, we're just hoping they know what they're doing with putting U2 on that sign.
