I never put much stock in these sorts of listings as they are often fuelled by popularity or promotional advertising in some way.
Regarding Hasbro's pricing structure though. I have noticed in the podcasts I listen to that deluxe pricing in the US has gone up with prices approaching $15 now in some cases. while at the same time, if you shop carefully here you can deluxes for as little as $23 which while it's not equivalent it's much better than 5 years ago when a deluxe was $8 to $10 in the US and $28 - $30 here.
Keeping in mind the horendous import duties here and the scale differences in the two markets, it's not as bad as it could be. I think we have seen a change in the retail prices here, especially with the Deluxe toys. Whether that's a reflection of a change in Hasbro's wholesale prices or something else is anyone's guess.
Either way, I'd recommend against putting too much stock in a report by a company who's business is to create lists to be included in media to make it sell better so the advertising in the media is worth more.
