I completely missed that - great find!
Yes that is the upcoming UCS R2-D2 and the rumored "modular-style" haunted house. Soooo looking forward to the latter!
hope the house is a modular style - doesn't look like it connects but maybe its another corner? Reminds me of those amazing victorian MOCs posted recently. it'd also make a nice break from the fairly traditional townhouse look of the previous models - every town needs a 'monster house'
