The big box stores here took almost a year to stock the new cable. I think now they have cable with a grey L3, but I'm not sure. Hardly ever buy something like that, I prefer using conduit, especially where more than 3 wires are involved. Wiring a combined socket and 3-way switch with NYM is a PITA.
Grey 1,5mm2 conduit wire has been in stock for more than a year (rather 2), I already used it as a switched phase when we did our new wiring.
