I think, from what I read, that it came down to the fact that there was only a small market for a hand-made all stainless $6-8,000 grill. And,d despite the high selling price, the high labor costs made it something less than a home run. Meanwhile, they could stamp out Summit Platinums for a fraction of the cost - on existing assembly lines - and sell them much more easily. There just wasn't enough sales and profit to justify such a lofty flagship. A shame, but that makes the small number of Vieluxes still out there an even greater treasure.
It would have been nice if they had just taken the Summit Platinum up one notch higher with stainless, not porcelain plated steel in that firebox. If they had, I think we would look at the 2nd generation Summit Platinum with a lot higher regard - even if it lacks some of the rugged design on the 1st generation Summit.
