Starting January 1, 2014, SWISS will exclude general M&M members as well as frequent travelers from redeeming first class awards. Can we expect a similar step for flights with Lufthansa?

The decision to only offer first class award tickets on SWISS to Senators and HON Circle members was internal to SWISS. This decision, just like, for example, the different treatment of upgrade redemptions, lies within the individual scope of each fully integrated airline in the M&M program.
At this point of time Lufthansa does not intend to follow SWISS with these measures.
