Bubbles can burst.

Maybe this is just semantics, but that isn't a "bubble bursting" to me. Guitar Hero's sales steadily declined to the point where it just didn't make sense to continue with Guitar Hero 6 (or whatever they ended at). That was a reasonable cost-value judgement. The 3DS is struggles for a number of reason, the big one being everyone already owns some version of the DS and 3D isn't really worth the upgrade... but that isn't really a bubble.

Your examples in my opinion weren't bubbles bursting but simply market corrections. The products themselves ran a little high for a period of time, but the market corrected itself and the impact of their loss in the long run was rather minor to the industry as a whole. More of a fad than a bubble as at the time the products were something of value, they just over saturated the market or got played out, replaced by something new and shiny.
