60 GH Bitcoin mining

Should due the expected difficulty this fall make the jump on my April 2013 order of a 60gh unit to the MONARCH 600GH for 1960.90 incl sh/h? In other words should I simply punt over to the next generation at this point in time. (Also noting the best i can see the 60gh getting to me now is NOV 2013 ..and that is best case)

How did you came up with Nov 2013 for shipping of an April 2013 60gh order? They shipped first single on 13 Jun 2013 (~70 days ago), so far they advanced from June 23 to July 7 in 60gh queue (~15 days). They are advancing 1 pre-order day in ~4.7 real days. There is about 131 days until the end of 2013, so they will reach first of January 2013 pre-orders after ~615.7 days (roughly 1.7 years) with their current average speed. If they double the delivery speed, you maybe can see your unit sometime in 2014.

Actually, anybody who bought(pre-ordered) in July 2012 or later should probably upgrade to monarch. If competitors release more products in september, it will be impossible to get any profits from 60gh units already.
