Sony HVR-Z7E Camcorder Comments

I've been filming on the Z1 for over 3 years now and have been very happy with its overall performance and durability, its toughed it out in the bush from sudan to tanzania, often in very dusty conditions and has never let me down, sadly its time to move on and replace it with a new camera... The Z7 is very tempting, the changeable lens capability means more versatility, however the one element which seems to be missing in the reviews i have read is whether or not it is still pal/ntsc interchangeable, as this is a feature of the Z1 which has been most useful to me.... am i ingnorant, does the new format on the harddrive mean this is not an issue anymore???
