I wouldn’t be too sure at all, I picked up a very very cheap (brand new and boxed) Hp50g six months ago , and it turned out to be old stock that had a free 1GB MP3 player in the blister pack. (I know it was old stock because I bought the very same version several years previous to this recent one!)
The MP3 player is truly ancient compared to modern variants. The 1GB is a dead giveaway to its age.

Some stockists just stock a SKU and pay little attention to which version it is, it might have also changed retail hands several times before you buy it.
