Ninja Gaiden Trilogy: a collection coming to PS4 and Switch?

A major Hong Kong publisher and distributor has published a list where there is a collection scheduled for PlayStation 4 e Nintendo Switch entitled Ninja Gaiden Sigma Trilogy, which should go out to March 2021. The trilogy in question should include Ninja Gaiden Sigma, Ninja Gaiden Sigma 2 e Ninja Gaiden: Razor's Edge. At the moment no further details are available since we are talking about an indiscretion not yet verified, and in this sense Tecmo Koei has not released official news on the matter.

Ninja Gaiden Sigma was originally released on PlayStation 3 in 2007 as an extended version of the original Ninja Gaiden for Xbox. Likewise, Team Ninja later released Ninja Gaiden Sigma 2, an updated version of the sequel, for Sony's console in 2009. Infine, Ninja Gaiden: Razor's Edge was an improved version of the original version of Ninja Gaiden 3, issued for Wii U in 2013. The third game is remembered for being the first installment in the series not to be directed by Tomonobu Itagaki.

Ninja Gaiden 3 was negatively received by critics and audiences, and there has been no news of this historic series since then. Given the recent success from the Nioh series, it can not be excluded that the Team Ninja wants to revive the feats of the iconic Ryu. That this Ninja Gaiden Sigma Trilogy could it be the first step towards the return of the series?
