Game Source Entertainment, a prominent video game distributor in Hong Kong, recently hosted a listing for Ninja Gaiden Trilogy, coming to both PlayStation 4 and Nintendo Switch in March 2021. The listing has since been removed, but not before the internet captured the apparent mistake.

First spotted on Reddit, you can also reach a cached version of the Switch page which links to the PlayStation 4 listing under the "New Products" section of the sidebar. The product page notes that the bundle includes 2007's Ninja Gaiden Sigma, 2009's Ninja Gaiden Sigma 2, and 2012's Ninja Gaiden 3: Razor's Edge. Aside from a March release window, the collection is also slated to cost $40 USD. Whether this is a remaster or a simple re-release remains to be seen.

There's no mention of an Xbox One version either, although Ninja Gaiden Black, Ninja Gaiden 2, and Ninja Gaiden 3 are all playable on the console via backwards compatibility.
