They are not so active in the last days in bitcointalk for the first time. This probably means that they have a lot of things to do and if I see the achievements of the last month
its hard to believe what they did everything in this short time. So lets wait till they have time to inform us about the extension after mainnet.
(and grab some cheap tokens

)
They are more active on Telegram and GitHub.
A few days ago they launched the Dusk testnet. I tried to build a node, but ran into some problems. I reported those problems on Telegram which led them to discover some bugs which they fixed overnight and in the weekend. Most issues are already closed:
