PTC announced version 19.0.
I don't see it available for download yet, but I expect that will be soon.
At the announcement, I believe they said it will be availale on June 20, so we should see it Friday, assuming the schedule doesn't change.
Some weeks ago I received an email "PTC Creo 3.0 Launch: Critical Dates" on which Product availability is mentionned on June 23rd. We should be patient still for a couple of days.
Here's a document which compares the functionality between versions 14, 15, 16, 17, 18, and 19: http://www.ptc.com/WCMS/files/161685/en/2-Creo_ElementsDirect_Modeling_Version_Comparison.pdf
