DX Kamen Rider Birth Driver - a hit or a miss?

Yesterday I was watching the video stream from CSToys live in Matsuyama, Japan and as part of the routine unboxing and demostration, Regional Director Mr. S (Masaki Saeki) revealed the DX Kamen Rider Birth Driver. At first I was flabbergasted on how the Birth Driver looks. But slightly disappointed on how it works.

The aesthetically pleasing and almost an exact replica of the one you'll see in the show. (As of this post, I haven't seen the Birth Driver in action, I referenced these from the photos posted on the net). I never thought  green and gold comes together perfectly in one design. I guess its works well given the right amount of colors and where to place them. The belt comes with two cell medals - scorpion and crab cells. Insert one medal (any medal) and turn the golden knob which at first creates the transformation sound. Remove the medal and repeat the process will create 6 different sounds which depicts the added fire power for KR Birth. Insert two medals simultaneously will generate the final attack sound. LED lights changes for every transformation.6 henshin sounds and 1 final attack sound is ok but this one lacks variety. 

What I am disappointed about is that there is no difference whether you insert core medals or cell medals. The excitement stops there. I'm not sure how KR Birth will use the belt on the show but by the looks of it, what you see is what you get. Honestly, the Accel Driver has more variations and works well with other memories than Birth Driver's take on medals.

Will this belt be a hit or miss? Should the box say - for KR ultra-mega-ultimate die hard fans only?
