It's always hard to predict the future. IMHO IRDA has already mostly disappeared. Very few devices still have an IRDA port. It's been pretty much usurped by bluetooth. It is still used alot for debug/programming ports on things like electrical meters. Personally, I'd avoid designing something with IRDA and instead use wireless. If you are stuck with optical then perhaps you can just buy enough modules so you'll never have to worry about them no longer being available?
