Earlier today, Brickset uploaded an image of a new LEGO Creator London Bus (40220) polybag which features a double decker bus. There’s no word on how to obtain the polybag at this point as there is nothing listed on the LEGO Store calendar for July. We’ll have to wait and see if it is part of an August promo or not since the it goes great with the upcoming LEGO Creator Big Ben (10253) which will be releasing mid-June for VIPs and to the general public on July 1.
We’ll also have to see if this is a regional set or not as it does feature something prominent from the UK and we usually don’t get stuff like that here in the US. If it is, you can always build your own with the instructions but you’ll be missing the stickers for the advertisements on the sides of the bus.
