Can anyone new make a profit mining in 2014?

I looked up the specs on the new 3,000 GH/s Neptune from KncMiner and thought that it would make a great purchase. But when you try to work out the ROI, the numbers don't work unless BTC gets somewhere close to $2,000, you get the unit next week or you have solar panels.

$2,000 is possible, but that's a real speculative play given the $1,200 to $750 fall in the past few days.

Which is the way to go?
