If the games arent getting made ( at least in far lower quantities) people wont buy new graphics cards... I think we can expect to see more companies doing the same within the next 12 months.
Still a big market. Haven't ATI shipped 3 million 5 series cards and Nvidia 400,000 Fermi cards (although that includes Tesla cards so who many gtx470/480 is unkown
I think the fact that BFG were only getting a one year warranty from Nvidia and the delays and short supply was the final nail for BFG. WHen your market for the last 6 months is basically a fraction of 400,000 cards sold in total and you have to stand the extra 9 years warranty, it doesn't make economic sense.
