Insomniac has way more people, allowing them to work in 3 or 4 games at the same time.
Bend, Sucker Punch or Bluepoint have been growing but as far as we now they still are working in a single game at the same time (Sucker Punch may have a main game SP team + a smaller DLCs or MP team).
In the case of Bluepoint, their whole team worked on GoWR according to the game credits and many of their Linkedin pages, which show that after Demon's Souls they moved there. I didn't watch the GoWR Valhalla credits, I don't know if they worked there too. At least a few months ago they still didn't have a game design team big enough to lead their own AAA, and as they said that moved away from remasters and remakes, this means they'll continue as a support team for at least another project.
Sony always focus their marketing on games to be released in the next months, maximum a year and a half, with a handful exceptions. Big new AAA games take around 5-9 years nowadays.
Sucker Punch released GoT in mid 2020, GoT Legends in late 2020, GoT DC + PS5 version + Ikki Island DLC in mid 2021. So being optismistic their next game, likely to be GoT2, would release in 2025-2026, but could also take until 2029. So it means that very likely they won't show it until 2024-2025 being optimistic.
Bend released DG in 2019 and until 2021 they fixed it and released new content, and ported it to PC, in addition to help ND with TLOU Online and an Uncharted game that we don't know what happened with it (maybe is one of the SP games being developed inside ND now). In 2021 Bend started to work in their new open world IP that will use some of the Days Gone concepts. New IPs take longer, so 6-9 years is more likely. We're talking about a potential 2027-2030 release and to show it maybe in 2025-2028.
We also have to understand that since these games already started development in 2020-2021, they already had the PS5 devkits and specs since the start, so they will be PS5 gen games, so should look way better than the ones who started some years before. This means extra work, but at least they don't have their own next gen engine: both use Unreal Engine. This means that since April 2022 -maybe in their case a few months before since Sony is an investor of Epic- had Unreal Engine 5.
