No 2D->3D, but I've owned this TV for over a year and 1) I love it and 2) 3D is a once every three months type of thing. Unless you're a 3d-o-phile, you won't watch a lot of content in 3D. It's great for the first few weeks, good for animated movies, SciFi, and nature, but for most viewing, I'm just enjoying the 65 glorious inches of 2D. Glare is the most common deal breaker out there for sure.
I'm pretty sure the LG's have 2D->3D if it's a must-have feature for you, and they also use passive tech.
