"Anyone seen the design for the conformal tanks? I assume like others have said they will be part of the wing to body fairing. Similar to the F15/16 & 18"
No, that's not the case (and I don't think anyone here has said that it is).
"Conformal" here is being used in the sense that the RCT occupies the entire cross-section of the fuselage below the floor beams and so differs from a conventional rectangular-section centre wing tank.
Might not have been the best choice of adjective, feel free to suggest an alternative.
