GG's torque games page says this about it The Kidgroup/Hasbro version of Marble Blast is being contracted to Plastic Games to develop and enhance game play. It will then be ported to the NetJet online gaming system.
A few quick searches has revealed nothing but a single screen shot:
, pretty much no information about the game, and no videos.
Seems to be geared towards smaller kids but the thing is cheap so maybe someone here will check it out
Also along these lines, when trying to find more info about MB XP I found these three games which look similar to MB and kinda fun. Switchball (PC XBox360 PS3) Ballance (PC) and Roll Away (or Kula World) (PS and PS3 store download)
