Despite the VG industry being so big, what could cause another 'crash'?

Shovelware might be helping the game industry. I see piles of PS2 games in so many bins and say wtf are these games....so many weird games out there o.o but PS2 was the lead console. Now Wii may be getting those huge amount of wtf games in bins or maybe not still Wii is now the lead console and breaking records.
