I just looked it up - the Summer Review deadline was June 4th, so it has been almost 6 months since the first batch entered review, with nothing to show for it. The third batch will be entering review in a couple weeks, and so far we have seen no tangible results from LEGO, save for the Japan-only CUUSOO alpha stage that had 1,000 vote requirements and extremely short turn-around, and the Minecraft set, which was more due to the constant pressure from its fans and the support of Notch.
I'm starting to wonder if CUUSOO is actually going to manifest into anything more at this point, or whether it will go the way of LEGO Universe as another project that was grand in scope but poor in execution.
