its always difficult to predict what will increase in value.
if something is mass produced then it is less likely to become a valuable collectible.
just my guess, but of the current product line i would imagine the Custom shop Historics/Reissues and some of the artist signature limited editions (Page, Beck, Slash, Bloomfield etc) might increase in value over time.
mostly because those guitars are made in smaller quanitities and still have a lot of hand made craftsmanship involved. in some cases, the Reissues are better made than the original 50's LPs.
of course if something catastrophic happened, like Gibson went bankrupt or moved all their production to China then the recent crop of Reissues might have a price spike.
but i don't expect any of my guitars to increase in value significantly in the near future.
