If I suddenly found a big gold nugget, I'd follow the advice that's often given here - I'd keep my existing camera (Samsung GX-10 twin lens kit) and spend the money on a wide-angle lens; either the Sigma 10-20mm or the Samsung 12-24mm. I would also love to have a good A3 printer as, currently, I'm limited to A4. So I've said that I've no intention of upgrading my camera.
