Regarding the Metroid Prime Trilogy, initially released in 2009 on Wii and in 2015 via the eShop on Wii, we have news via Jeff Grubb of VentureBeat and Video Games Chronicle. Containing Metroid Prime, Metroid Prime 2: Echoes, and Metroid Prime 3: Corruption, this compilation would be expected on Switch and According to Grubb, development is complete, which VGC sources also seem to confirm. Nintendo would have decided to delay the release of this new version while waiting for the right moment to announce it and launch it. Jeff Grubb is sure of his facts, but cannot say exactly why Nintendo is doing so. However, he thinks that the constraints imposed by the pandemic, particularly in terms of quality assurance, have played:
The game is over and Nintendo is holding back. I think the Metroid Prime Trilogy is over and whether Nintendo is releasing it now or later depends on other factors. I think one of the big issues for Nintendo during the pandemic was managing QA… In my opinion Nintendo was focusing their QA resources on one or two big projects at a time and that meant some games that were concretely completed were put aside (for questions of priority). Japan is still grappling with these issues, so I don’t think these processes will be back to normal anytime soon.
The VentureBeat reporter adds that he is very possible that Nintendo will keep the compilation for the communication campaign around Metroid Prime 4. For the moment, the firm is focused on Metroid Dread, which will bring a conclusion to the 2D arc of Samus Aran from October 8th. However, let us keep in mind the recent statements of Mike Wilkan, former developer at Retro Studios, who considered that‘Porting Metroid Prime to Switch would be quite a complicated business. The answer can only come from Nintendo anyway, be patient.
