Personally, I really like it. It looks massive and proportions are not awkward like in the leaked pictures.
Few let downs: price (I'll wait for a discount, 500 EUR is max what I am willing to pay). Tracks were not being used from 41131. It does not look like LR13000 but perhaps it is a compromise to have this set safe.
I don't care about the length of booms, it can be easily extended (it is still LEGO at the end of the day).
