The only really concrete information we have is the (re)start announced for 2021 Tomb RaiderThe creators responsible for the series are still guilty, but at least one new visual detail has now emerged – but that's probably not really meaningful
On the recently redesigned website for the series you can find Lara Croft's motif above by solving a puzzle – she looks pretty much like she did in her early days when it comes to equipment and outfit. This also happened not too long ago with her guest appearance on Call of Duty had been hinted at. However, how much this represents what your design will be in the new game is questionable, because a comment was promptly made to the Spanish website Vandal that the motif should not represent exactly that…
Otherwise, no further details have been revealed yet, so we only know what was already known: The game is supposed to cover the events of the “old” trilogy (plus sequels, we assume) and the “Survivor” adventures since then to somehow reconcile the reboot is being developed with the Unreal Engine 5 and at some point the publisher will not be one of the (still) numerous Embracer branches, but Amazon Games.
