Horizon became the best selling PS Studios game ever, this is the reason of why they milk the IP. And yes it got discounted, just like all the other games. Its sequel was having the same sales than the first one until they did an experiment of including a top game like this one earlier than usual on PS+. That obviously did affect its sales, but did help PS+. Horizon CoM did a great job being one of the flagship PSVR2 showcases, bringing a major Sony IP to VR.
And yes, AAA take several years to be made. Nowadays on average between 5 and 9. Which means that since Horizon 2 was released in 2022, Horizon 3 will be released pretty likely between 2027 and 2031. Pretty likely closer to 2027.
Horizon Online is being made by a separate team since 2018 leaded by the former Killzone MP director and former Rainbow Six Siege director. So may be ready to be released next year or so.
Sony GaaS MLB, Gran Turismo 7, Helldivers 2 and Destiny 2/The Final Shape are very successful. Concord and Firewall Ultra tanked, as some non-GaaS tank from time to time. A few got cancelled for different reasons, as non-GaaS also get cancellled from time to time. Sony will continue with the remaining GaaS and non-GaaS, no changes there.
