From that list (and since it's for 2013) I'd have to go with the DX13 (BD T-800)
But fo me a very honorable mention goes to two others....
MOS Jor-El the amazing sculpt and the great execution on the soft goods make this a great release. Just can't stop staring at this figure...
IM3 The Mandarin Another stunning likeness here and like Jor-El, a masterful job with the textiles and outfit. Chair's a nice touch too.
And although they weren't "in the running" this year, I picked both of these up and they're both great, detailed figures that are great adds to my collection...in this year or any...
CA:FA RED SKULL Out of the park on quality with both head sculpts and while the color is off for the uniform, it's tailoring is pitch perfect. And that overcoat...wow. So glad I didn't let this one go by.
AVATAR Jake Sully The size, the detailing, the whole execution here is just pure art. A lot of great engineering and thought went into this piece...great detailing and an overwhelming presence on the shelf.
Here's to 2014...and with some of the pre-orders on the way...it's looking to be a good one!
