Earlier in the week, Android Police published leaked slides from chipmaker Qualcomm, revealing that the Android "K-release" will be announced during "spring 2013".
This is thought to refer to Android 5.0 Key Lime Pie, the next version of Android that is rumoured to be a more significant step forward for the mobile software than the recent Android 4.1/2 Jelly Bean iteration.
A spring release window suggests that this would coincide with the Google I/O developer conference, scheduled for May 15 to 17.
But after posting the slides, Android Police and several other places that picked up the story were told to remove the information by Qualcomm.
There could still be nothing to the story, but the fact Qualcomm moved so quickly to stop it suggests the spring release could be true.
Google typically introduces its major new Android generations alongside a mobile device using the Nexus branding. But it is unclear which manufacturer will partner with Google for Key Lime Pie.
Some reports have suggested that Sony has secured that privilege with a handset codenamed LT30i.
But the firm has already unveiled its new Android flagship, the Xperia Z. The phone will be released later this month, and it's unlikely Sony would want to crowd it with a Nexus model just months later.
Instead, Google could turn to Motorola Mobility, the smartphone manufacturer which it purchased in 2011 in a $12.5 billion deal.
Google has given assurances that it will not give preferential treatment to Motorola over its other Android partners, but it has already made Nexus devices with Samsung, Asus and LG.
It has therefore been suggested that Motorola's rumoured X Phone featuring a 5-inch display will debut alongside Key Lime Pie.
An unnamed source told Droid Forum last month: "Supposedly, Motorola has been working hard to create a UI that both compliments & enhances the Android experience, and is intended to be Nexus-like."
