Hmm, I definitely need to come up with another way to denote this. The timeline will start to get useless if so many models stretch out all the way to 2019. It breaks the "replaced by a successor" kind of relationship that makes all the fun.
Certainly most calculators are still begin sold in some country. I definitely want to note this in the timeline, but I think the boxes should follow the evolution in a single place to keep some coherence. It would be France, but not by design, rather because I virtually have information and experience only for this region.
I'll delay my update until I sort this out. I thought this would be an easy matter, but it turns out to be non trivial.
