If the laminate is made like normal plywood with grain alternating directions on adjacent plies, then over time, the expansion and contraction of the grains work against one another, and it will tend to pull itself apart. This is more true if the thing is outside - inside it will last considerably longer. If the laminate is made with the grains running the same direction, then it will last about like a solid piece, assuming the glue lasts.
A solid piece of wood does age - it gets harder, stiffer, and lighter as the moisture dries out, and the resins crystallize. This make it more resonant, which is generally a good thing in an acoustic instrument. This is very well known not only in acoustical circles, but carpenters (and anyone who works on old houses) know it too - young studs, you can drive screws into, and they go in without complaint. Old Fir studs will, when you drive screws into them, literally scream at you, because of how the wood changes - it is VERY different acoustically - it's not at all subtle, you can easily tell the difference listening from next door.
A laminate, as it has glue at every interface, even if the grains are running the same direction, that glue will not dry out or crystallize over time like lignin (the natural "glue" in wood) does, so it will not "age" as much acoustically.
