no 1080p 60 3d?

According to the just released HDMI 1.4a spec, there's no 3d support for 1080p @60hz.

The maximum resolution is 1080p@24hz

1080i @ 60hz is supported though.

Keep in mind that we're actually talking frame rates, not refresh rates. Hence no mention of 120hz.

Yes, this is pretty common. Films are usually filmed at 24 fps. When you watch a movie on an old crt tv, they often did a technique known as 3:2 pulldown to artifically create 6 additional frames per second to fit the tv's "30" frame per second operating rate(hz) but it disorts the image and gives some people headaches when viewing 3D content. Hence, you won't see 30Hz as a supported resolution much anymore.

In regards to the 120hz thing, it comes to the bandwidth available and signal degregation. I think right now, the 1080p hdmi can only carry a signal a maximum of 50 feet without having a booster/repeater. With 2560x1600 resolutions, the maximum distance is something like 40 feet. I imagine with 120hz at 1080p having to send twice the data through the same cable, you'd run into even shorter maximum distances and it would be troublesome for most installers. Its also important to recognize most 120hz tvs dont support 120hz input and just take 60hz and mathematically merge the frames to create 'inbetween' frames for the effect of added smoothness.
