@Mark Dewis While that may be the case there has been more news recently regarding STLs than plastics and right or wrong some folks are getting the impression that WGA is focusing on STLs right now. You can see that in the comments on Dakka Dakka pretty clearly.
Personally I do not think WGA is avoiding development work on plastics while focusing on STLs but I understand how some folks might get confused and think that given how much more vocal WGA has been of late regarding STLs.
And while some folks like STLs because they intend to use them others actually dislike STLs in general, not just WGA STLs because they reflect work put into something they themselves will not personally ever use. I am in neither of those groups but I understand both.
The WGA rep on Dakka Dakka is making a decent effort to deal with this but what WGA really needs is more news on the plastics. In particular explaining in detail why some sets are taking so long.
