One other thing to note is that there is some speculation about the new Red Ranger figure (with the Green Rangers shield) on display being a reworking of the 8" Classics Lion-O mold. I compared the two figures side by side (SDCC 8" Lion-o and the new Red Ranger figure) and the muscle tone on the legs do match up.

Edit: Welp, the 'mystery" line from Mattel was "Watchmen" so it looks like we've seen all we're going to see for Thundercats at SDCC.
