Preempting this to say, this is meant to be some light-hearted speculation. It's been some time since there was an update, so i'm sure people have plenty of theories (and wishlists) about what is to come in tomorrow(?)'s update. Like shaking Christmas presents to guess what's inside.
I suspect we will be getting the mole market upgrade previously featured in the roadmap; and maybe the achievement system as that was the last update. I would really like to see changes to the reliance on huge amounts of moonstones for profession/den upgrades - at least for the early upgrades. I'd also like to see more rotation in the mole market; including basic cooking supplies like salt and pepper being available all the time. Getting really greedy, i'd also like to see a repricing of most of the moonstone items in the mole market (and possibly more items costing pebbles) - for example, I would have so much fun using pattern changes if they were cheap, but I cannot justify spending $6-12 on changing one pattern layer. I think it would go a long way in rebalancing the usefulness of moonstones and pebbles.
