I'd pretty much agree - once you have debugged sample parts in your hand, production quantities are
usually not far behind.
Remember that many companies sometimes announce products speculatively to gauge interest & see if
it's worth actually making them.
Unlike the likes of Motorola, Microchip tend to target the less-than-collossal-volume market, and so
once a part is in production it is pretty rare to have supply problems.
