I'd love to know, too. What we observed at Sematext was that 4.0 SolrCloud very very buggy and difficult, so I suspect there aren't many big Solr 4.0 based clusters out there. 4.1 is much better (thanks Mark & Co.) and I'm looking forward to 4.2 in March.
Also, based on the stats we have access to via SPM ( see http://sematext.com/spm/index.html ) I can tell you that ElasticSearch clusters are, on average, quite a bit bigger than Solr clusters in terms of nodes, which I find interesting, but not surprising -- if you look at http://blog.sematext.com/2013/02/25/poll-solr-cloud-or-not/ you'll see less than 40% of Solr users are SolrCloud users, which kind of explains it.
