QuakeBLAST (not Quakewave) arrived today. The video reviews noted that the hoses pop out, but that seems to have been fixed as there are locking grooves on the hoses.
The only negative so far is the white plastic tabs on the legs.
Edit....
Spend the day playing with him. If you already have a purple Quakewave, then this figure probably isn't for you. But if you want a MP style Shockwave, then this fits the bill, and is better than Quakewave. QuakeBlast is more detailed and the lower legs are leagues better in every way compared to Quakewave. I only have the grey Quakewave, but QuakeBlast looks much more impressive side-by-side. Fingers are more robust (my Wave hand broke) with metal pins and thick joints.
The metallic purple paint is well done, with no cracking or flaking.
