Its awesome and i simply want to title it:
you should really click here and watch it in full HD
it has a ton of upgrades! lots of exciting new accessories and possibilities. i love the sharper image, bigger sensor, 10fps higher rez photos, 120fps video! and lots of other stuff. and i think its cheaper than the old one. crazy! if you have been wanting a GoPro now is the time. im sure it will sell out super quick.
