Monopoly Hotels Adding Ponies?

Over on the Monopoly Hotels facebook page (an iOS game for those that aren't sure), it looks like some form of pony content is on the way.  This is a teaser image they tossed up with the quote:

We have some really exiting content coming out next week! Based on this picture, what do you think it is?

They haven't dropped anything else yet, we can't be sure what exactly is planned.  Hell, it could just be a closeup image of a pink and yellow amoeba.  I've seen some weird ones. 

What do you guys think it is?  Maybe we will see an Equestria edition with various pony buildings for sale to play with?

Thanks to Diego for the heads up!
