I still think that toys in general are a short term investment. There will likely be a few figures that retain value, but overall, toys are produced in such numbers and you have so many collectors with MOC collections--you just didn't have that in the 80s. That rarity drives much of the toy market value. Plus, I haven't seen a ton of kids with MU collections, so you may not have the nostalgia factor ten or twenty years from now, either.

The next thing might be seamless joints or Disney infinity-style electronic components or figures that stores actually sell ;-). Who knows? That's why I open and play with my toys with my son, because it doesn't matter if he smashes my vision and firestar together. They're just toys after all--that's where their value really is.
