hard to say…depends on if Metroid Prime 4 will be cross-gen. If it is, then I could see a reveal in February/March with launch in late-September. If it is not, then I don’t expect the system to be revealed until after the game has launched…which’ll prolly be in April/May. So June/July reveal with November launch seems plausible.
They could also just delay the reveal until 2026…NSW is still selling more every fiscal year than any year of literally any of their systems excluding Wii/DS/GBA.
