My guess is January, 2015.  Most Titleist products are on 2 year rotations, and the next set of balls due out are the non-urethane (non-ProV series) lines like NXT Tour and DT Solo - at the PGA Product Show in January 2014.  Most testers, self included, have been guessing the test ball with the red numeals is the replacement NXT Tours.

I agree with Don, however they will need to update the packaging and add 2014 instead of 2013!

Packaging has already been changed over.  From what I have been told, there are no planned changes for the ProV series in 2014, only a box cover change.

I love that Titleist is on a 2 year plan for everything.  It makes it easy to play the latest greatest stuff.

Josh, I agree...2 year upgrades make so much more sense...compared to competitors that are changing every 6 months I do not think as a consumer I could ever stay ahead of the curve and feel good about my clubs and balls! Thanks Titleist for being not just a leader in the industry but also smarter how you approach your product life cycles!

Cheers!

When you make the BEST Golf ball, it has to be hard to improve them. Leave it to Titleist to come up with new innovations, then test them, and release them. I still have a dozen and a half of my shipment from last year, and I love 'em. I can't think of a better ball then the Pro V 1's I'm using now. 

  Thanks Titleist

I'm just replying here hoping to find the name out for the test balls too. I love them!!!
