As you can see Sunwayman updated their horrid clip to a decent Titanium version that screws into some pre-tapped holes in the tailcap. Otherwise the light looks the same, the body does appear to have some different machining and the grooves look deeper compared to the original V10R Ti, but the heatsink, mag ring, bezel, and tailcap look the same. Hopefully the Veleno Designs Tritium replacement parts still fit perfectly (Bezel, Heatsink, Bodies, Clip, Switch) as I've got those coming for my XP-G, but depending on which I like better they may go to the XM-L.
As you can see here the Ti+ comes with the Titanium switch that was on the Ti2's. That should mean that the Veleno Designs switch will work.
Here's the last few pictures:
