I think there are several things to remember about the toy shop.
Firstly, it is six years since it first became available. That's a new generation of children to enjoy it.
Secondly, the original set was made entirely from existing easily available pieces. No new prints, except possibly the carol singers' heads, and even then I rather doubt it. No new hairdos. No stickers.
I'd argue that the original toy shop was a pilot to see how the theme went, including that wonderful hand build teddy bear, and that's why they pushed the boat out more and more through the rest of the series, including what is arguably the best Lego house ever.
I'd certainly suggest that the new version is an attempt to address the shortcomings of the original set, such as the very small number of lights on the tree, the small number of toys available and the absence of a sticker on the sign. The bear isn't an improvement, but hey, you can't blame them for using a premould when it exists.
In the end, it's not about us, much as I am sorely tempted to order the missing pieces to convert my original toy shop into the new one. It's always about the children, who, as ever, are the main customers.
If the new version doesn't sell well, they won't do anything next year; if it goes well, they will either rerelease or improve the bakery. Much as I would love to see new Winter Village sets, I think that's the end of it now, and to be fair, I've run out of space to display them and not risk divorce. ;)
I will therefore be buying something else. Maybe the Mercedes Arocs truck.
