PS4 VS Switch lifetime sales, which console will sell the most?

PS4 of course. Switch is going to do very well, but not 100m+ well. Assuming the switch follows a traditional generation route and not incremental upgrades.

There is nothing traditional about Switch, and Switch will definitely have multiple revisions probably including upgraded version.

Well if Switch does follow a model similair to phones, (an upgraded version every 2-3 years? No real cutoff point for the "Switch".) Then any comparison of sales other than launch aligned is pointless, as are any predictions in this thread.
