CanAm's strategy makes sense. Cover all the bases in a generic gun that many people would find interesting:
Bullpup: T97
High-end bullpup: Tavor
Pump: Grizzly of various barrel lengths and magazine types.
SXS: Backpacker
Semi-shotgun: Cougar + Turkish AR thingy.
For pistols and main battle rifles there's Marstar's M14s, various norinco pistols, M4rgery and other odds and ends. Never mind your vanilla Glocks, Sigs, S+Ws, Rugers and other "brand" names already covered by the other dealers. Let's not forget SKSs and CZs from the Eastern side of things.
I don't really see what else the market can absorb in the below 2000$ price point. Sure there will be many one-offs, that some people may buy, but your meat and potatoes are pretty much in the above list.
