Just had a look at the translated website there are 4 models, HS300, HS200, TM300, SD200

HS300 with a 120GB HDD and SD Card
HS200 with an 80GB HDD and SD Card
TM300 with a 32GB SSD (as far as i can gather from the google translated Japanese) and SD Card
SD200 with SD Card only

they're pretty much all have very similar features, the HS200 and SD200 lacking a couple of features, the HS300 and the TM300 being the top models both basically the same camera but one with SSD Storage instead of a HDD

no 720p recording as far as i can tell.

I'm surprised no one has mentioned Black Silicon or SiOnyx as a potential exotic material for the new sensors. Obviously there aren't enough Engadget readers in the Red forums

QWhat is also needed is side by side specification listing of the known features, and include the new samsung that was also announced today but seems to have gone mostly unnoticed but most mostly due to the buzz surrounding the Apple WWDC
