[Q] Is is worth to upgrade from Note 2 while waiting for Note Pro 8"? topic

Hello, I have a Galaxy Note 2. I don't find the need to upgrade to Note 3. I use the S-pen often to write notes and use the devise to read/annotate pdf. I also take photos very often and sometimes videos as well. I also use the voice recorder. I found the screen of the Note 2 a bit small. I have to change my glass and zoom in all the time. I have been waiting for the Note Pro 8" but disappointingly Samsung only announced the Tab Pro 8" without a S-pen. I suppose that in the summer or later this year, they will make the Note Pro 8" available. At that time, I will certainly buy it. Between now and then, I am considering whether or not to trade in my Note 2 for the Xperia Z Ultra. Any opinions appreciated.
