From what little information that is out about future tablet releases from samsung, it doesn't seem likely that there will be another tablet in the same 8.9" size range. As other users have stated above me in this thread, it generally seems like the tablet fields are being centered around the standard of 7" and 10" sizes. The only exception that has officially been stated as a definite release to come is the new samsung galaxy note 8" they showed off at MWC show not too long ago. Personally I can't wait for the US release of the 8" note because even though the galaxy 8.9" is awesome and maybe even perfect in its size, the only tablet I love more than my galaxy tabs of all sizes (especially my tab 7.7" and my tab 8.9") is perhaps both of my galaxy note models (the note 2 phone and the note 10.1" tablet) as they are simply just great devices in general and the addition of an S-Pen is just pure Awesome all around. So an 8" note tablet of what is already a great device in every size/format, just makes it even better to me.
So if I were you I wouldn't hold my breath waiting for another samsung tab in 8.9" form, just buy the note 8" when its available and enjoy the addition if an S-Pen wth great performance as well.
