Update: Looks like they took the page down for the UK.
There are numerous reports of the 21303 WALL•E being delayed through LEGO Shop@Home and Brand Retail due to the neck being unable to support the weight of the head. The video review by The Brick Show documents the issues pretty well. I have a few choice words about that neck issue which I’ll save for our own review. As of this writing, the set should be listed on the Shop@Home website, but right now going to the product page just shows a “product not found” message but it is available in other countries like the UK. It is presumed that a service pack will be created to address the neck issue. I’ll update this post with any more information on availability once I get it.
