Meh. I took a closer look at the box in that Instagram photo and it's still not that exciting to me. I did notice it looks like the background sky of the mansion picture appears to have a holographic effect, with maybe a shifting color effect. That at least does tie into the overall game design better. What's funny is that in black and white it reminds me of the Bate's PSYCHO house.
I see what you mean about the card backs. Yes, there will likely be bonus cards, so the playing cards will likely have the mansion, maybe even with the holographic effect seen on the box (nah). And looking more closely at the suspect cards, the blue background is gray, so I suspect the weapons cards to likewise be gray. It's funny it took a monochrome depiction to link it to the LGE in my mind, but it's not the primary card back so that's probably another reason I didn't notice the similarity before.
The box is certainly capable of holding a proper tray insert, and both the 50th Anniversary, and more recently Secrets in Paris, had them. Unlike he 50th Anniversary there's no tin that doubles as a dice cup to hold the weapons, just a cloth bag, so that doesn't bode well for an overly accommodating tray solution. And the box extreior looks very similar to Secrets in Paris construciton.


Still for this price a nice plastic insert would be helpful, and the box seems thick enough to have one. Then again, I'd already feel cheated based on the tokens alone. I wonder if there will be a more complete rule book, as included with the U.K. Edition, not to mention the 50th Anniversary?
I'm sure you're right that the promo artwork is just mock ups. That holds out hope that the weapons tokens are the full-sized ones which came with MD and the 50th editions. And maybe the pawns/tokens will be nicer? Maybe even the Cluedo ones? I'm still frustrated that they haven't included a Mrs. white card as an option (particularly for this monochrome edition), now that we know they have the artwork and backstory. Especially since there's an optional poison card and token -- no reason not to have an optional character card. Since they detective notes in the photo don't have 7 suspects, I'll assume that's a lost cause. What we need is a picture of the box back ...
One final though -- isn't ToysRUs a big European brand store as well? If so, why no Cluedo "exclusive"? Is is just a US only exclusive?
