Update: We've heard from Samsung that this page was put up by Amazon by mistake (aka, it was set to auto-publish), and has since been taken down. If you submitted an order, it'll likely be refunded in a short time, if it hasn't already. We can still take something from this, though - the Note 10.1 is coming soon (probably next month), and it'll likely be $550 for the 32GB version.
As we now know, it's packing a 1.4GHz quad-core Exynos chip, a handy stylus slot, and 32GB of internal storage. Amazon is showing a ship date of 3-5 weeks, so you can likely expect the Note 10.1 to be officially released some time before the middle of July. The Amazon listing also has some hilarious typos (though it is official - shipped and sold by Amazon):
Processor: 1.4 GHz Quad Core Xeon
- Size: 32 GB
- Manufacturer: Flash Memory
- Speed: 5400 rpm
To get your pre-order on, just head over to Amazon now.
