Dude in this article says so..... So its gotta be true...
I hope not, because Key Lime is supposed the most epic of all.
But then again, I can see Google releasing a New Nexus 7(3) for the reveal of Key Lime.
I assume this will launch aside an updated Nexus 7, with updates heading to the Nexus 4 and 10, but I'm more interested in the OS upgrade here. I imagine that since that since Google preserved its Jelly Bean title with its latest 4.2 upgrade, Key Lime Pie will be a major update a.k.a. Android 5.0.
