They didn't want put the focus out of the last guardian that's why it whas not on e3 show i think.

In the e3 trailer of gravity rush 2 was still written 2016 as release date...

this game looks pretty impressive, its not my style of game, but maybe i would end up getting it.

probably something that gets more attention at gamescom, tgs and/or psex. looking forward to it.

New details (but still no date)

Keeping Things Light
Speaking of goofy — even though Kat may find herself in peril and situations may take an occasionally serious turn, Toyama-san is all about keeping things fun.
“We wanted to make a positive, upbeat game, but that naturally manifested itself from the concept of controlling gravity,” explains Toyama-san. “It may have been a bit too strange having the story go too dark from that idea, so making it vibrant was something that just gelled.
“There are more than 50 side stories that have nice comedic moments that bring personality to Gravity Rush 2. For example, one mission has Kat becoming an action star for a movie, which is filmed in-game. It’s all very light hearted, as you would expect.”

"Gravity Rush 2 is a reminder that E3’s best stuff isn't always in the press conferences
The action game was one of this year's best — and best-kept — secrets"

I'm pumped! Between this and TLG, Japan Studio is really on a roll.

Release date will be given in less than 2 weeks

I feel like this game is going to bomb though, I'll buy it for sure but not alot of people bought it on the PS4 and the fanbase were mostly on the vita.
