totem basic cam - new vs old style

I hear about new vs old style totem basic cams, which are already pretty new. I'm not sure what the difference is. How does one tell? And what's the difference?

I have read the blue is only available in the "new" style, is that true?

An inquiring mind wants to know. Can someone help him out?

New ones are lighter, have different grip or teeth pattern on lobes, have slicker look with ergonomic trigger and color anodized part where trigger wires attach . Overall pretty similar.
