The gap between 155M and 162M is pretty big - 7M so the chances are very big that Switch can finish in that gap exactly .. 7M for the last years of it's life may be 2 to 3 years of sales .. Also passing the 160 or 162M isn't the only case where there won't be debates. Not reaching 155M is the another case where debates won't be made too.
