Of course Sony are going to be there. And we'll be covering their every move. Most of which will probably come from company head Kaz Hirai. Interestingly the keynote has already been entitled "New Tactics For 2009"; if Sony's new pricing plans don't come into fruition at next months GamesCon, then expect to see the PS3 Slim at TGS.
With some massive conferences planned over the next few months, it's probably an exciting time to be following Playstation. But please remember to manage your expectations, many of Sony's big announcements were revealed at E3. Don't expect too much and you might be surprised.
