Does Sony have a bigger game after the God of War 3 release?

[EnosStory]

Unless they announce something at E3

Its clear they have cleared the schedule for GT5, they know releasing their own games around GT5 would be suicide.

To me its them positioning GT5 for all out war with Reach and Natal. Its especially a way for Sony to increase their market share in Europe where GT5 will be unstoppable. NA will see some other games before or 2 months after GT5.
