Hello @KCL allow me to jump in and bring some clarity:
The (original) idea of portfolio diversification came from protecting our treasury against volatility. But we realised than it was not appropriate to diversify the main DAO books without doing a SIP. So we focused on diversifying the OPERATION budget only as all of the bills we receive are in either in FIAT or stable coins. That is why, from an admin team project 
it became a SIP. We submitted the idea to Animoca that was glad to draft a SIP, and submit to the community. The curation took a really long time (months indeed, with different authors coming and going for diverse reasons) and the original idea was about buying millions of APE. Thanks to the effort of the PM team and a great collaboration with Animoca, we reduced it to something more “digestible”, especially for a first SIP.
Now on to the NFT collection: A parallel project to bring TSB NFT collection was already in the works. This was confidential informations and was not shared with the Animoca team. It was irrelevant as we had little confidence about the transfer actually happening. We have made great progress last week, and managed to unlock the situation, which is why we shared the good news, especially because there was a connection to this SIP. We are staying neutral, but also want to make sure that all the relevant information is shared for the community to vote in good conscience.
Believe me, I would have rather have completed this piece of work sooner! Remember the SIP-9: Mandate for NFT collection management? That was back in July last year, and that is when we started to work on the idea of transferring the collection. That is how long it took, and getting the motion passed at Sandbox board was no small feat: it’s an expensive collection
