The last Samsung Galaxy Note 10.1 was released over a year ago and it's time for another one. References to a Galaxy Note 10.1 (2015) have appeared on Samsung's official site, specifically that three apps support the tablet. And it's not a typo either, the Galaxy Note 10.1 (2014) is listed as well. Not that it's a big surprise that Samsung will be reprising one of its models.
We can speculate, of course, at this point a 64-bit processor is not unlikely and it's an easy guess that the new tablet will incorporate the improvements in the S Pen of the Galaxy Note 4. Whether Samsung sticks to LCD or makes the switch to Super AMOLED (based on the Galaxy Tab S 10.5 screen) remains to be seen.

Last month, Motorola and Qualcomm confirmed that a new Moto flagship smartphone powered by a Snapdragon 810 processor would be introduced this year. Most likely, this will be the next-gen Moto X. If a recent rumor is to be believed, the new Moto X could be "smarter than any other smartphone", though for now we don't know what that might mean.
