There will definitely be thought put into whether to create a new theme, and a decision will likely be made as to whether to create and utilize such a hypothetical theme that will result in a new theme here on the forum unless the decision is made not to or no decision is actually made at all. If there is a new them, it will likely be light, unless of course it is dark or medium. It may or may not end up being the default, if it is even made, which it likely will be, unless it isn't. There may be multiple themes, unless there aren't. Hope that helps.
