Very hard to predict. In practice, a port of eCos to any particular
16-bit processor is unlikely to happen speculatively. More likely,
either a chip vendor will decide that it would be a good way to grow
market share, or a major application developer will consider it a key
element of a product strategy. Then they either do the work
themselves, hopefully contributing it, or pay for somebody else to do
the work.
