Do you mean the 10 inch version of the Galaxy Note or the 2nd generation of the 5.3 inch current Galaxy Note?
I'll assume you mean the 2nd generation of the 5+ inch Galaxy Note for now. While there is no firm confirmation from Samsung rumors have targeted October for the release of the new Galaxy Note. Some of the features that have been bandied about for the 2nd generation include a 5.5 inch Super AMOLED display with a souped up resolution of 1650 x 1050, an Exynos Quad Core processor, the latest version of Android Ice Cream Sandwich which will be 4.1. Interestingly the 2nd generation Galaxy Note is rumored to be seen by the company as a competitor to the Iphone 5 which will also reportedly be released around the same time in October. It should be quite a battle.
