Might be quite a few years tbh, seeing that you can't event get USB sticks using them yet. MRAM seems to be the furthest along and a lot of research is going into a new variant called SPRAM.
I think the biggest MRAM chip commercially available at the moment is only 4 Mbits, although 32 Mbit SPRAM chips have been made in research labs. So give it time... probably 5+ years before we see commercial products.
MRAM/SPRAM will also be a competitor to DRAM though so you may well see them replacing system memory before they replace storage. As they're non-volatile technologies, a computer with MRAM/SPRAM internal memory would be truly 'instant on', i.e. if you turn your computer off then back on again it will be exactly where you left it without having to rely on hibernation etc and would match or even beat the performance of current memory modules. (Doing the same with Flash would be pretty awful as it's so slow compared with the DRAM used at the moment and would die pretty quickly from too many write/erase cycles)
