Which would you buy (Panasonic cam)?
 

They are selling the TM750 for around 1300 USD and then for 300USD less (At 1000USD) they are selling a TM650. The difference between the 2 is instead of 96GB internal memory, it will have 64GB internal (Still be able to put in more SD cards in though). And then the 5.1 mic is replaced with a stereo mic.

I wish I could see some test footage of both cameras in use but I can only get the TM700 or TM750 footage. The TM650 is a Japan release only and having trouble finding stuff. At least from what I understand it's only released in Japan.
