So I just installed 1.2 and noticed the DLC download options are gone in the launcher menu. Anyone know if this is intentional? Initially I thought maybe it was gone because all the DLCs are included and assumed the Polish sound pack was among them, but that doesn't appear to be the case.

Assuming you have read patch notes, you would know that all DLCs released so far are part of the patch 1.2 (even the pre-order ones). As such said option is not required (quite possibly it is simply hidden) until additional DLCs are released...

I guess I didn't make it clear enough that I'm aware of the inclusion of DLCs. However, the Polish sound option is not in the configurator so it's probably not included, therefore making me wonder why the DLC option is gone altogether.

Cannot answer the question as I already have had the Polish subs/voice overs downloaded before patching to 1.2.
If you do not have them it is possible the DLC option appears back.
Or maybe it was removed for the duration of this patch as the design team is reworking the back end of it for the future...
It is true that the DLC download menu is no longer available, by now everyone can confirm that, so this should answer your initial question.
