Console sales for year that successor releases:
DS:14 Million
Wii:4 Million
PS4:7 Million
GBA:15 Million
GB:4 Million
3DS:7 Million
Based on this, I think a reasonable sales figure for the Switch for the fiscal year where the successor launches is around 7M.
The GBA sold extremely well the year the DS came out even though the DS was backwards compatible. However, the GBA was only 3-4 years old when the DS came out and hasn't reached a point of saturation yet and was retailing for 80$ compared to the DS's 150$, which is a significant difference.
The DS sold well, but it did this before the 3DS price cut, after sales fell off a cliff.
