When the 8GB variant hit "out of inventory" status, Google told the Verge there were no plans to restock it, despite the promising "please check back soon" following the ominous inventory status. This of course lead to speculation that the Nexus 4 price drop was really more like a clearance sale.
The Verge has confirmed with "a trusted source with knowledge of the company's plans" that Google has no plans to restock the 16GB Nexus 4.
Update: It looks like the Nexus 7 LTE variant is now back in stock.
Does this mean an impending reveal for the new Nexus phone? No one can say for sure, but one thing is beyond doubt – Google is pressing exactly the right buttons to make this Nexus season particularly excruciating.
