I personally think the title is a bit misleading, as in suggests that they are not, when I think the only one of which more consoles is being made is the GC I think?
Also, the current support is nothing compared to the PS2 (their main rirval last-gen, which still has fairly large support and sales), so in comparison to that, they are nothing but "dead".
One person's experience or opinion never shows the general consensus
