This is pretty much what I expected when I heard the event was canceled, so it comes as no surprise. Walmart is showing the price as $249, and they are also carrying the 16GB model for $199 (here). Again, no surprise.
TBH, that's not the news I wanted to see today. I was hoping that someone might post a product page for the Nexus 10. While we do know that this tablet will reportedly have a 10.1" screen (2560x1600 resolution) and run Android 4.2 on a dual-core 1.7GHz Exynos CPU, a pair of cameras, 16GB of storage, 2GB of RAM, it would be nice to finally have these details (and the price) confirmed.
But I don't think that will happen today. I also cannot find any sign of the Nexus 7 3G model, though that would be more likely to be sold via the telecom partner or possibly Best Buy
