Well this is going to make things interesting, in a lot of ways (not all of them good)!
Still, I've got a few examples of things that I'd be keen to rework into fully fleshed-out templates, if it means making a bit of dosh for my troubles.
Also, here's hoping that this is a precursor to the long-overdue "modularity". Not holding my breath for it, but it could fit in very nicely with a proper asset store.
EDIT: beaten to the punch, but I think Spongehammer and myself are on the same wavelength about this.
