So, the short answer, is probably not any time soon.
Longer answer is that XF1 themes and XF2 themes are fundamentally incompatable. We are unable to just lift a XF1 theme and drop it into XF2. What is worse is that many of the beloved themes we had before the migration have no XF2 versions, and the websites where we grabbed/purchased them from no longer exist. So, we are trying our best to get things into a working state that is within the "it is change and I hate it" realm instead of the "I actually cannot use this" realm.
Even longer answer is that what I've found out so far is that themes in XF1 and XF2 are some weird amalgamation of CSS, HTML layouts, and code that is all combined together. The selected theme is then served out to the user in a final html page and CSS that is made from that amalgam. From what I've gathered, enough has changed in how themes are structured or in the component parts I mentioned that updating a XF1 theme to XF2 or even just lifting the CSS portion from one to the other is non-trivial.
As far as other things going on, well, we just got the dice roller back online and working, amongst a ton of other small things.
