 They're already investing into these games, PS4 titles are in development. 

 

Do we know this or is it speculation/rumour?

We know it. http://www.gamesthirst.com/2012/03/14/report-guerrilla-games-crytek-hiring-for-next-gen-consoles/

We know plenty of third parties are, but Guerilla Games is first party which makes them more notable. Similar story for Sucker punch I think.
