Japanese news site Quiter has posted a list of games expected to be shown at this year's TGS; this list is by no means official and comes from a mix of real information, rumors, and sheer anticipation. Those titles marked with a "?" have no official status for TGS exhibition at this time. And just to stave off rumors, while many fans are hoping for it, there probably will be no announcement of Dragon Quest VIII.Sony
