A player who did the whole season on an iPhone and wants to enter a regional now needs to buy or borrow a Switch before registering [3]. The battle they play will be the same battle. Hoshino says all of the battle calculation is done on the server, which is what makes cross-platform play possible in the first place [5]. The device in the player's hands supplies a screen and an input method.
That separates the thing being pitched from the thing being gated. The pitch is parity: the same game on both platforms, with the choice coming down to what you own and whether you prefer tapping [2]. The rule gates the picture of the match, not the match itself. Regional events and above are streamed on official channels [6], VGC drew the largest audience of the four games at Worlds this year according to Esports Charts [7], and the finals ran at the Chase Center, only the second time the finals have been held in an arena [8]. Hoshino's stated reasons, that graphics "are quite nice on the Switch 2" and that letting people bring any of the many phones out there gets complicated, both sit on the presentation side [4].
The handbook already carries a remedy for a presentation problem. Competitors are required to bring their own devices [10], but the rules say team IDs may be used on hardware provided by the tournament organiser for streamed matches [9], and a team ID reproduces a player's team on another account [11]. A phone player on stream can be handed a Switch for that match.
Scale keeps this from being a crisis. In Unite, where the mobile build is allowed at high level and has worked fine, only one player in this year's finals appeared to be playing on a phone [12][13]. Pokémon Go exists only on mobile and its competitive matches are streamed the same way VGC's are [15]. Champions is the one competitive Pokémon title that stops the phone at the local rung [19]. The mobile build had been live for at least two months by the time it was kept out of Worlds [18].
The evidence contains no technical reason. The Verge put that question to Hoshino and concluded there is not really one [17], and the answer it got, given before the September 1st rules refresh [4], describes a preference about how the game looks rather than a constraint on how it runs. The Verge's reporter grants that Champions is sharper on Switch 2 than on an iPhone 14 Pro, in a series often criticised for its graphics [16].
For anyone shipping one product on a second platform, the grid worth drawing has two axes: whether the platform changes the result of the task, and whether it changes what third parties see of the result. Neither, and the parity is real, so eligibility should follow it. Display only, and the fix belongs to whoever owns the display, not to the user who has to go acquire a console. Result changes, and the honest move is to say which result and gate on that. Both, and you have two products with two rulebooks, which is defensible so long as the marketing stops calling them one game. Champions sits in the display-only box, and the September 1st rules let local organisers act on that while regionals keep the old line [3].
