For Fire Emblem Fortune's Weave Switch 1 compatibility, the answer is that Nintendo lists the game for Nintendo Switch 2. Game Rant's platform report explicitly describes it as a Switch 2 exclusive and says it is skipping the original Switch. An original Switch purchase should therefore not be made on the assumption that this title runs on that hardware.
What the official listing establishes
Nintendo's U.S. product entry identifies Nintendo Switch 2 in its system field. Its supported TV, tabletop, and handheld modes describe ways to play on that system, rather than versions for different generations of hardware. The modes do not establish compatibility with the original Switch. Match the listed system to the console you own before comparing offers.
Why older Switch games can cause confusion
The Game Rant report discusses the series' earlier original-Switch releases before explaining the new game's platform choice. Those older games provide context for why players ask about Switch 1, but their availability does not prove that Fortune's Weave has the same requirement. The relevant evidence is the new title's own system listing. Our guide hub covers Fortune's Weave separately from those earlier entries.
Physical and digital listings need the same check
The Singapore Nintendo page identifies package and download versions while still naming Nintendo Switch 2 as the platform. A digital offer is therefore not evidence of an original-Switch edition merely because it appears in an online store. Likewise, a physical case with a familiar series name should be checked for the actual system designation. The format choice and the hardware requirement answer different questions.
No assumption about future ports
The official listing and release report describe the announced platform, without establishing whether a future port could ever be made. Forum hopes for a downgraded version are not a product announcement or a compatibility test. The listings also do not describe save transfers or an upgrade entitlement from another Fire Emblem game. If the listed platform fits your setup, the route overview is a separate way to assess whether the adventure interests you.
