That is probably total BS, just like previous years.
I see little point to revive Heavenly Sword since it was a total commercial flop and Sony had always God of War to fill that segment on it's library.
Last guardian coming for the end of this year, highly doubt it, Sony would make a complete fanfare leading to it and to this time nothing has been show.
And then people will get all delusional about GT7 or whatever, only a year has passed since the last instalment (not even a year), and it would be pretty stupid from Sony's part to an announce a new game or even compete with all that is coming out later this year, as it would be equally stupid to remaster GT6 on the PS4 while some of it's stuff is being and it will be implemented, same for a tech demo of it since they showcase that in the GT Academy rounds, they probably will struggle to get such a port running by 2015, probably for GT Academy.
Let the stupid hype machine begin with credulous people just eating everything trolls can throw at them and then be underwhelmed by what it will be actually shown.
