To me the biggest "unknown" with Percona is that MariaDB (the company) bought out Codership (the creators of Galera Cluster, which XtraDB Cluster is based on) and it doesn't seem to be OSS any more.
I'm sure for some shops this will drive them to pay for the same feature in MariaDB cluster, but I'm more likely to just transition to MySQL Group Replication.
This is my whole point about MariaDB - they are steadily making their OSS software completely dependent on the company (paid) versions for anything beyond toy scale.
