It does not appear that Nintendo is interested in launching a successor to the 3DS anytime soon (if ever), so I think the chances of the Switch hitting 100m are very high.
I expect Nintendo will keep the 3DS in production for some time, as they seem to see that as a more ideal option for younger children for whom the switch is too heavy/large and/or too expensive for parents to risk a young child carrying with them. But for older kids and adults, the Switch will be both the home console and portable option going forward it appears.
