Arrays in shells generally suck (and behave quite different between different shells, e.g. zsh arrays are nothing like bash arrays), so I hope they don't make it into posix. OTOH, process substitution is a perfectly elegant and nice feature that fits well into the original design of bourne shell, removing an obvious limitation of pipes. It also behaves pretty much the same across shells that have it, so it should be much easier to standardize.
