According to leaker py_rates_, Chitose Abe's fashion label will introduce four new iterations of the running-inspired hybrid sneaker in Spring '21. So far, only mock-up photos are available, but it does provide fans with what to expect for the upcoming "Black Off Noir-Off Noir," "Dark Iris/Campfire Orange-White," "White/Sail-Sail," and "Sesame/Blue Void-White" makeups. The leaker account also reported last month the label is also working on two iterations of the Blazer Low that is expected to drop early next year, but there's currently no indication that both silhouettes will be releasing together.
As of now, the brands have yet to confirm that the next wave of Sacai x Nike Vaporwaffle styles is releasing in Spring '21.
UPDATE (01/27): Thanks to @Hanzuying, here's a closer look at the Sacai x Nike Vaporwaffle collab in the "Dark Iris/Campfire Orange-White" colorway slated to release sometime in the spring.
