OK, here are my guesses: <img src="/images/graemlins/cool.gif" alt="" />

1. a fixed version of the RSK within the next two years.
2. a larger version of the PSP within the next two years.
3. an emergency shelter/bivy within the next three years.
4. a laser or strobe signalling device within the next three years.
5. the RSB (Ritter Survival Book) within the next five years.

Any hits? <img src="/images/graemlins/grin.gif" alt="" />
