While checking 3GPP TS 36.306, I noticed some new LTE categories have been defined. We now have all the way up to category 14. I also noticed that Wikipedia page has up to Category 15, not sure how/where they got it from.
The LG Space page has some more details for anyone interested in exploring further.
A Qualcomm demo from MWC for LTE Category 11, if interested.
