So, tel me if I'm wrong:
1- There is no especific agenda or schedule to deliver the equipment.
2- The difficulty Mh/s is potentially growing on Litecoin.
so
The equipment devalues each month acording to it's performance/income.
so
if the dificultty average increases 15% a month
and
the equipment arrives in about 9 months,
probably
people buy a peace of junk (the hardware don't pay itself in the further months, and, further more, the simple work will be a loss).

Conclusion: it's a 3D high-risck 

That's the way I think
but I wish I'm wrong to those already spend their money on this (supposed) hardware.
