Motorola has not yet decided whether the entry-level Motorola Moto E will be the recipient of the new Android build. The device is powered by a Snapdragon 200 processor, but does come with 1GB of RAM.
So far, we have heard from HTC, and Motorola in regards to the next Android build. HTC said yesterday that it will update the HTC One (M8) and HTC One (M7) within 90 days after receiving the final update from Google. While Nexus devices and the Google Play edition handsets will receive the update first, in a competitive market for flagship Android devices, HTC is hoping that it can spur sales of the HTC One (M8) by promising to make the Android "L" update available to its top-shelf model, as quickly as it can.

UPDATE: As it turns out, the Motorola Germany page cited above was a fake. Motorola issued a statement saying that the Facebook page was not real, so the information about the Motorola Moto X and Motorola Moto G getting updated to Android L should not be considered legitimate.
Thanks for the tip, Joe!
