Bearing in mind the normal lifespan/shelf life of macro lenses and given the fact that it is Canon's newest one and the only one with Hybrid IS, I'd be shocked to see it replaced/upgraded in the next ten years.
Believe it or not, they are somewhat 'due' for a new FF macro lens:
(EF macro lenses per Northlight)
1987: 50mm f/2.5 Compact Macro (1:2)
1996: 180mm f/3.5L Macro USM
1990: 100mm f/2.8 Macro (1:1)
1999: 65mm f/2.8 Macro (5:1)
2000: 100mm f/2.8 Macro USM (1:1)
2008: 100mm f/2.8L Macro IS USM (1:1)
On the budget-ish side, Canon values getting people into macro photography, so a solid 'starter' macro lens in the $250-500 range is needed. I've heard the non-L 100mm is a good sharpness-per-dollar lens, but the starter 50mm compact macro seems to have been left behind. Perhaps that's for a reason, but perhaps a refresh is coming?
On the pricey side, as stated before, the 100L is great as is. So an update to the 5x (an unbelievably specialized piece of gear) or -- more likely -- an update to the longer 180L (or something in the 150-200 neighborhood) might be warranted. I seem to recall the 180L lacking fast focusing, IS or weather-sealing -- we can debate if those are
musts for what is a more dedicated macro lens, but certainly the lens could be improved.
