Speculation:
PS1 on PS4 might be announced. Back in May Sony filed a trademark for G-Police, a PS1/PC/PS3 game https://euipo.europa.eu/eSearch/#details/trademarks/015448715
And just today they trademarked another PS1 game, Lifeforce Tenka https://euipo.europa.eu/eSearch/#details/trademarks/016110538
Also, back in 2014 Eurogamer already reported that PS1 and PS2 support was coming for PS4 http://www.eurogamer.net/articles/digitalfoundry-2014-ps1-ps2-games-heading-to-ps4
