The spec at www.sony.net says:
"* NTSC / PAL compatibility depends on region"
...
Image size (pixels) 1080 60i-compatible
(NTSC)*
AVCHD: 1920 x 1080 (59.94i recording, 29.97 fps image sensor output / Average bit rate 17 Mbps)
MP4: 1440x1080 (29.97 fps / Average bit rate 12 Mbps) , 640 x 480 (29.97 fps / Average bit rate 3 Mbps)
...
1080 50i-compatible
(PAL)*
AVCHD: 1920 x 1080 (50i recording, 25 fps image sensor output/ Average bit rate 17 Mbps)
MP4: 1440 x1080 (25 fps / Average bit rate 12 Mbps) , 640 x 480 (25 fps / Average bit rate 3 Mbps)
So, since 25 fps is closer to movie standard, its better not to buy these cameras in NTSC regions like USA.
The luminous-landscape site has explanation on why 24 fps is better.
