When we got our first look at Samsung's Note 10.1 with S-Pen at Mobile World Congress back in February, it was packing a 1.4GHz (presumably Exynos) dual-core processor and oversized S-Pen. And, unlike its little brother, it was also lacking a place to store the S-Pen in the tablet. A few weeks after that, rumors began surfacing that Samsung had taken the Note 10 back to the lab to swap the dual-core processor for a quad-core variant, as well as add a place to store the S-Pen into the chassis of the device.

At an event back in late May, Samsung unveiled the new Note 10.1, complete with 1.4GHz quad-core processor and a storage slot for the S-Pen. Now, XDA forum member floiancu has somehow gotten his hands on a prototype version of the device and shot a couple of videos, giving us a good look at the hardware, S-Pen, and Photoshop Touch.

Unfortunately, we still don't have any potential pricing or release date information, but floiancu notes that "the fact that [he] had access to one, it can't be far off."
