We all thought that Samsung would announce the LTE Galaxy Tab 8.9 at IFA in a few days, but they decided to go ahead and announce it now. The announcement also included the affirmation of the 1.5 GHz processor inside of the Tab. It is not known if the 1.5 GHz processor will also be in the Wi-Fi only version of the Galaxy Tab 8.9. For some reason I doubt it will.
No other details are known at this time. Hopefully Samsung will announce price and availability at IFA.
