The Nintendo Switch can run games that are technically too powerful for the system. This was put to the test when Capcom published a streaming version of Resident Evil 7 for the Switch back in May, and now Ubisoft will try the concept with Assassin’s Creed: Odyssey. Like the Resident Evil release, this will be in Japan only.

The announcement was part of Japan’s Nintendo Direct, not the one here in the U.S. Kotaku noted (citing Siliconera) that Phantasy Star Online 2 had been streamed for the Switch in Japan back in April, as well.
