The Note 8 2014 is overdue, and I can only hope that a refreshed tablet is coming out soon. The original offered an excellent form factor and specifications considering the limited tablet options that included an integrated stylus. A refreshed tablet, perhaps using the newer 8.4 form factor and possibly an amoled screen, would be welcomed by many.
Seeing that the current version was announced in february of 2013 and released in april of the same year we probably should look to that as the schedule for a new release. I love the Note 8 and am hoping it has a successor.
