Although we will be releasing an OGL edition of SWMA, we don't have current plans for another Rolemaster edition of the SWMA - we'd much rather (and I think Terry would much rather) be producing new stuff such as the Shadow World Player's Guide and Emer III, and of course Terry's adventure contributions to The Guild Adventurer.
In terms of a print version of Xa-ar, we've agreement in principle to have it printed through ICE, but there are a handful of practical issues that ICE need to sort out at their end.
Best wishes,
Nicholas
