According to a source inside of Sprint, the wireless carrier has officially placed the LG Nexus 5 on the end-of-life list. That means that Sprint won't be promoting the N5 in its stores, though any stock that's still in retailers or sales partners will probably remain on sale in at least some capacity. It also means that Sprint won't be sending out any more standard software updates to the phone.
Of course, that's not as big a deal for the Nexus 5 as for other devices, thanks to the developer status of the phone. Like other Nexus phones and tablets, the N5 gets its updates directly from Google, even when those updates include features specific to Sprint. (Oh, sorry, Verizon Galaxy Nexus owners. Didn't see you there.) Sprint has routinely announced new Nexus 5 updates, despite their Googley origin. Since the Nexus 5 uses identical hardware no matter what carrier you happen to be using it on, the updates from Google (including Android L) shouldn't be affected. It does mean that Sprint is unlikely to send any network or feature improvements Google's way.
Sprint is the only CDMA carrier to support the Nexus 5. Whether or not they'll pick up support for the next Nexus device, whatever that might be, is up in the air. Note: the screenshot above refers specifically to the white version of the Nexus 5, but we believe all models have been given EOL status. It looks like the non-customized version of the Moto X has been shelved as well.
