For the swedish market there is usully a new loco from Märklin every year, at least a new livery on an existing model. And other european manufacturers like Roco and Heljan also produce their locos in 2-rail and 3-rail versions. So the availability of rolling stock is actually in favour of the 3-rail system. Some of the Märklin models become available from Trix as well, but not all. And it is far easier to convert a 2-rail loco to 3-rail than the opposite. I think the situation for most european countries are the same, except for the really small markets - where 2-rail may be easier to find. And in the US there is a totally different situation with many 2-rail models.

Many europeans 2-rail users claim that the choice of models is better in 2-rail, and that may be right: If you look for the very expensive hand-made specials from small companies, and also for the cheapest "hobby" models. But in the mainstream segment where most people choose to buy their locos it is not a big difference at least.

Looking at the price tag of a 2-rail vs 3-rail model may of course be a reason to choose the 2-rail. But in many cases the difference can be that the 3-rail verson is digital/only available with sound etc...
