As you may remember I recently mentioned they internally added Jan 30th two SFV DLC to Steam so I thought they may be released very soon. Not DLCs like a game update, a new character or a new stage. In this particular case, I'm talking about the DLCs you see in the Steam or PSN stores, like costume or stage bundles, game OST, season pass or CPT bundles.
But after investigating the upload date and release dates of all previous DLC, I see that is very unlikely that they may be released soon. Instead now I think they are more likely to be released (just a guess) around March or April, but it's hard to make a prediction because the times vary a lot for each group of DLCs uploaded at the same time.
For the 18 already released DLCs uploaded to steam servers after the SFVAE release they spent an average of 67.5 days between their first upload/creating and their release date. The fastest took 24 days and the slowest took 161 days. 6 of them, including the recently uploaded, remain unreleased.
For the 16 already released DLCs that were uploaded/created between the SFV and SFVAE releases, needed an average of 133 days to be released. The fastest were released the same day they were uploaded, the slowest took 519 days. 3 of them remain unreleased.
P.S.: When I say "uploaded" I mean that they created a Steam app for this DLC that later may be updated adding content and data. Until they are released they use this "SteamDB Unknown App" placeholder name to keep its content secret. I don't have info about their content and can't datamine them because they are unpurchased DLC so I can't download it.
For each DLC you can watch their story of upload and changes using this URL
https://steamdb.info/app/989970/history/ and replacing the number for the "Steam DLC code" mentioned in the table.
I got the list of DLCs from
here, where you have a list of changes for the whole Steam SFV game, that also includes these DLCs. Notice that from time to time they mention

Text in green means they added it in this entry, text in red means they removed it.
Next thing I'll investigate will be the SFV app itself, the time spend between each time they release a new version to their QA servers for testing and a new game. Hopefully, if the follow a fixed patter may help us know when can we expect the next game update.
I didn't realize we had a hard release date. Now the random update w/ the achievements make more sense.
I saw it here, we know it should be released during "March 2019".
