Some information about Obi-wan Kenobi teased in this article by Star Wars Sessions, who claim to have sources close to the projects. (I didn’t think it was suitable for the rumours thread, as there’s nothing specific - just stuff to hype you up for the series)

EXCLUSIVE DETAILS REGARDING OBI-WAN KENOBI AND ANDOR by Matt Hudson

Regarding Obi-wan Kenobi, they claim ‘the studio is “raving about Kenobi” (whereas the chatter around The Book of Boba Fett has been muted in comparison). They are going as far as to say that Obi-Wan Kenobi is “being billed as the biggest Star Wars event of the past few years and the next few years also”.’

The source also says “All generations of fans will be catered for…this is truly transitional Star Wars”.” This lines up with what we’ve heard about potential Clone Wars flashbacks, with the characters being closer to their versions in the original trilogy, and perhaps an Inquisitor cameo or two from Star Wars Rebels as well.
