do you know if hasbro is going to have a reissue of the original landspeeder
If by "original" you mean the vintage version, then Hasbro has already re-released that back around 1995/96, when the modern line started. Hasbro used the same vintage mold, but spruced up the paint applications a little bit. Only $10 for one of these at the link Chris posted above.
But they won't ever be reissuing a "vintage" version again, technically. They likely won't even be reissuing the modern update to the vintage version either, since they finally created an all-new, and more accurate, mold for the Landspeeder just a few years ago. So any potential Landspeeder reissues will likely come from that newer, revised mold instead.
But if you want a real vintage one, you should scope out eBay (like the link John just provided), or stop by CloudCity.com
and have a look. Plenty of them out there to be had...
Good luck with your search.
