My first ever pre-order was MMr - then I pre-ordered The Hobbit.
With time the MMr preorder is looking less attractive...MM prices in the UK are coming down and as a result I think I may get a good deal on an original which I would prefer, an original will be easier to repair in the long term.
I'm keeping my deposit on MMr LE for now, our distro guarantees refunds at any time, even after WMS approval. I'm secretly hoping that PPS will announce something special for the LE to please the early buyers (check out their website blog faq: "LE- Other(tbd) - Standard No Other(tbd)").
As for the Hobbit, we've seen what happened with WOZ, expectations of delivering on time have been lowered. But build quality and theme are hugely promising....I think it will be worth the wait, roll on 2015.
Good chance I will back out of the MMr and stick with the Hobbit.
