There was a time when the Nintendo DS was a pretty sure bet as far as sales were concerned but publisher Ubisoft has gone on the record stating that the DS market is shrinking.
The company's UK boss Mark Slaughter had this to say about the sorry situation:
Overall, for everybody there is a decline in the DS market in its entirety. So instead of that being a growing market, within Ubisoft we have to find out how much of that pie we can actually defend.
Ubisoft is probably feeling the pinch more so than other DS publishers because it has invested so much in its line of casual games, usually involving puppies or babies. Or both.
