An interesting snippet emerges from the Nvidia annual stockholders' meeting-- the company is working on Kai, a "strategy" (if not a reference design) for cheaper, more powerful tablets carrying Tegra 3 processors.
As VP Rob Csonger says "Our strategy on Android is simply to enable quad-core tablets running Android Ice Cream Sandwich to be developed and brought out to market at the $199 price point."
A means for vendors to beef up the Kindle Fire competitors, then? Perhaps. But back at CES 2012 Nvidia presented the ME370T, a quad-core tablet co-developed with Asus with a $250 price point.
We haven't anything about the ME370T since then-- perhaps it will be reborn with Kai branding? If not, Nvidia might simply usher a new range of cheaper Tegra 3-powered tablets.
