I highly doubt they will switch plans. This current solution seems far from any real productive use.
Compare to the battery industry which has frequent announcements of new solid state or natrium batteries, but there is still much investment in “old” lithium ion batteries since they are proven to be productive and they are also approved to be used in products.
Assassins Creed 1&2 are not really open world games comparable with BoTW or ToTK. The world is much smaller and everything is far more linear. The combat system is also not extremely great. You can mainly just wait for counters constantly.
That said, I still enjoyed the games (especially 2) a lot. But it is more the fun climbing action and fairly good storytelling.
Skyrim might be possible, but I have not played it personally. The witcher is available on the Switch as well.
