News on Future Monogatari Adaptations?

I have heard that Akiyuki Shinbou would like to adapt the other seasons but is there any actual confirmation that Shaft will (eventually) adapt all the Monogatari light novels?

The problem here really is that Shaft as a company broke apart, and key people left. Here's a "post Shaft" stack showing which projects key personal did meanwhile: https://myanimelist.net/stacks/17594

In a nutshell, https://myanimelist.net/anime/50346/Yofukashi_no_Uta was directed by https://myanimelist.net/people/15639/Tomoyuki_Itamura who is the person really doing the work on the Monogatari franchise. The real question should be thus: Now that Shaft broke apart, which Studio can and will pick up the pieces to make sure we get more seasons?

I have indeed heard of a few key people leaving Shaft and creating anime like Kaguya-Sama: Love is War (which also explains the Monogatari reference season 2 has) but Shaft has still made a promotional video for Monogatari last year https://myanimelist.net/anime/51068/Manga_Bakemonogatari_Shaft_Seisaku_Tokubetsu_PV showing that they still can recreate the Monogatari aesthetic (this time following the art style of the manga). Shaft is also creating a new Madoka Magica movie https://myanimelist.net/anime/48820/Mahou_Shoujo_Madoka%E2%98%85Magica_Movie_4__Walpurgis_no_Kaiten which they probably couldn't do if their company really broke apart. 

Although besides that it is interesting to think of which other company could tackle the Monogatari Series. Former Shaft employees would have to surely be on board as well as the producer Aniplex as they would have to give permission for the creation of new seasons in the first place. As the interest stack you've linked shows, former Shaft employees have gone to quite a lot of different studios.
