Just received this from Apple.

Dear Developer,

As we announced in October, beginning February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK. Beginning June 1, 2015 app updates will also need to follow the same requirements. To enable 64-bit in your project, we recommend using the default Xcode build setting of “Standard architectures” to build a single binary with both 32-bit and 64-bit code. 

If you have any questions, visit the Apple Developer Forums. 

Best regards, 
Apple Developer Technical Support

Actually, I don't think it is only for new apps.  Everytime I submit a update to an app iTunes shows me this warning.

Well, that's reassuring.

It affects us, and probably others in this forum, because we are planning to release a new version of our app targeting a specific vertical market sometime in February.

"R&D at Embarcadero is working on a 64bit iOS compiler, oh well actually 2 of them, also C++. We'll support 64bit and "universal binaries" (bundling both 32 and 64 bit binaries) requested by Apple.
The Feb 1st requirement is only for new apps, not for updating existing ones, but still we are trying to make a solution available by that time.
The roadmap describes the entire year, more than the individual release. This time around we are trying to have it public by January, covering what we expect to deliver in 2015."
