IMO, I would be very careful regarding any invested $$$ in TTDZ at this point in time.
Lots' of unconfirmed, unvalidated PR fluff has been released by TTDZ over the last 3 months and NOT stated communication can be collaborated, validated or confirmed other that the forward statements that TTDZ has provided.
AIMHO of course but then again looks like the TTDZ 0.004's are getting ready to line up!!
