These Titans may have decent ROI if they are actually able to mine Scrypt-N.

But there will be a ton of hashing power incoming as all these Titans are delivered.

So I think my vote is to return for a refund instead of ultimately waiting 10-15 months (estimate, if ever) to ROI.

EDIT: And all those Antminer L1's may start hashing in December/January, making it even more difficult to ROI. So my vote is definitely to return for a refund.
