A factor that is often overlooked concerns the issue that there might be a significant difference between the present-day and the initial mass of the most massive stars - as a result of mass loss. The upper-mass limit may be substantially higher, possibly exceeding 200 Msun. The issue of the upper mass-limit will however remain uncertain as long as there is only limited quantitative knowledge of mass loss in close proximity to the Eddington (= Gamma) limit. For this reason, we present mass-loss predictions from ","authors_text":"A. de Koter (Amsterdam), G. Graefener (Armagh), J. M. Bestenlehner (Armagh), Jorick S. Vink (Armagh Observatory), N.
