UPDATE 10:00pm ET: EB Games have deleted the Tweet in question, and Street Fighter series producer Yoshinori Ono has stated that a Switch version of Street Fighter V "does not exist right now".

Whaat!?
No way, where can I get this product?
... Could it be that we didn’t realize that someone are making it?
;D

Such item does not exist right now.
Thanks! https://t.co/0hYBet71aR

The "Champion Edition" of Street Fighter V refers to the rollup of all of the prior seasons of DLC for the February 2016-released fighting game. Capcom have admitted publicly in the past that Sony provided funding for the game's release in exchange for console exclusivity: prior box arts for the base game and the January 2018 "Arcade Edition" promoted the game as a "PS4 Console Exclusive Game". Other exclusivity deals in the industry have lasted for a period of four years, such as with Lego City Undercover on the Wii U (2013, published by Nintendo) compared to a multiplatform 2017 release (published by WB Games).

The EVO Japan fighting game tournament is running this weekend, and the finals for Street Fighter V are scheduled for 1630 JST. An announcement may come at that itme, but is not guaranteed.
