Instead of shooting in the dark, I would advise you and others to read what Frontier actually SAYS as it is available in their Annual Report online. You might be surprised to see that their strategy is actually quite clear and that you don't need to guess... They don't give roadmap specifics, of course, but you can pretty much see where they want to go and, more importantly, that they believe Elite is in a sweet spot of the industry, meaning they don't plan to downsize it.
Unless I am missing something, the only things said about Elite are:
"FY21 saw the announcement (in June 2020) and release (in May 2021) of
Elite Dangerous: Odyssey on PC, our most ambitious development project
to date: the addition of first-person on-foot gameplay into our 1:1 galactic
simulation of the whole Milky Way. This meant bringing the human scale
to a galaxy nearly 100,000 light years across. Completing this large and
complex expansion without the benefits of face-to-face collaboration was
challenging, and despite a successful alpha period, unfortunately the
launch was hindered by connectivity issues [

], and this turned the positive
reception of the alpha to one of negativity. Despite its initial challenges,
hundreds of thousands of players are enjoying the experience. I am
delighted with the underlying achievement by our team, and remain
confident that more and more players will upgrade to Odyssey over time
as we continue to refine the experience."
&
"Our existing game franchise portfolio continues to perform well.
Engagement with our Elite Dangerous player community
is gradually improving, and we remain confident that more
and more players will upgrade to Odyssey over time as we
continue to improve and refine the experience."
&
"We continue to support Elite Dangerous and our player community,
and look forward to more and more Commanders stepping up to
engage with Odyssey over time."
&
"In May 2021 we released our most ambitious expansion to date for Elite
Dangerous, Elite Dangerous: Odyssey, which generated
launch revenues on PC in that month. The overall reception
to this major content update has been disappointing, but we
are confident that as we improve and enhance the Odyssey
experience we will see more and more Commanders
engaging with the expansion."
I found
nothing in the annual report that sets forth any sort of roadmap for the future other that a hope that put-off players will eventually adopt the DLC after some non-specified updates. Did I miss something? Because that does not inspire confidence that FDev have plans other than getting EDO into sufficient shape so that more commanders "engage" with the expansion.
