Nobody's confirmed that it's an adventure path yet, yeah?
It could be an Anthology book a la Candlekeep Mysteries and Tales From the Yawning Portal, too (though I imagine, if Ghosts of Saltmarsh fits this same mold, that the next Anthology book would be 2023). It also could be just a setting released in June, a la Mythic Odysseys of Theros.
What we're not getting is the next AL season until August/September, especially given that Critical Role: Call From the Neverdeep is our Spring (non-AL) adventure path. And it's HIGHLY unlikely that the AL is taking a sojourn to Krynnspace for this year's AL season. I also think the timing suggests that DragonLance is a Q4 release, with Spelljammer a Q2 release. So we'll get our Adventure Module in September like usual, Spelljammer or DragonLance in a brand new format and the other in a normal setting or anthology format, with Spelljammer in May/June (likely June to give space for the solo-release of Mordenkainen Presents: Monsters of the Multiverse). Then Starter Set: Dragons of Stormwreck Coast in July or August, and then AL-related module in August/September, with DragonLance in October/November/December. And probably at least one more NEW product in Q4, and at least one holiday gift-set/special edition set in Q4, too.
