Yes it's a threat, look :
Home consoles/handheld
6th gen : GC 22m+XB 25m+PS2 158m=205m / GBA 82m
7th gen : Wii 101m+X360 85m+PS3 85m=271m / DS 155m+PSP 81m=236m
So during this period there are more and more gamers but with the development of the smartphones, tablets etc.. a part of the gamers leaves their consoles and the sales decrease:
8th gen predictions : Wii U 25m+Xone 50m+PS4 100m=175m / 3DS 80m+PS Vita 20m=100m
