So, I got curious and did a little bit of digging and looked at the sales of the DS and 3DS before and after they got their first revisions, the DS Lite and 3DS XL, respectively.
DS/DS Lite:
Before - 43,765
After - 124,286 (+184%)
3DS/3DS XL:
Before - 43,291
After - 239,273 (+453%)
Just to get an idea of what Switch sales me look like on the week it launches, which is 3 weeks from this update. Hopefully, we're looking at something closer to the 3DS XL than the DS Lite, though I'm not sure how to tell which way or the other. Furthermore, after the big spike it got this week thanks to the new Switch model, we also have to see how far it will fall of the spike. These next 3 weeks are going to be very interesting.
Edit: I should also note that the 3DS XL launched alongside New Super Mario Bros. 2, just like how the Switch Lite is launching alongside Link's Awakening.
