You make a good point. I do think $6 million sounds light. Very light, in fact. So I dug a little further.
I imagine Predator makes most of its money from cues, though it is of course branching out. Let's say it only got revenue from cues. Predator would have to sell 6,000 cues worldwide, at a cost of $1,000 each, to get to $6 million in revenue.
I've got to figure Predator sells at least 25,000 cues a year in the US alone. Maybe 50,000 or more worldwide. That would put revenue at $50 million a year before the sale of accessories.
Throw in cases, chalk, clothes etc. Maybe that's another $15 million to $25 million.
Looked at it this way. perhaps $60 million to $75 million a year is a conservative estimate. I'd guess $100 million in annual revenue would be toward the higher end.
