If Microsoft releases a larger hard drive in the future...
 

Will games I dl'd and stuff be transferrable? Anything similar happen with the original x-box? I never got an x-box because it was shit.

Nah, the hard drive in the original xbox was internal. Also, the original xbox when modchipped with a bigger drive was fucking awesome.

Im sure if they release a new drive they'll make a USB adapter or something. Or go buy a xbox hard drive adapter like me :p

i have a 250gb usb hdd, how can i get that to work on my 360

I dunno
