Heh, ...no. I was asked the other day "why haven't we heard anything about Battle Tag?" and took a trip to the near-deceased Battle Tag Forum to check up on signs of life. MikeApostol wrote this there:
...by all accounts no one has heard anything from Ubisoft about this system since many many months ago. I doubt they are continuing to work on this. I wish they were, but the lack of action or communication with them (not to mention taking it off their online store) seems to speak more than their silence. It's really too bad because it's such a great system and with a little more tweaking on the hardware and software side it could be near perfectI'm calling this system dead. Way to kill your own creation, UbiSoft. Sadly between that system doing a faceplant and Light Strike not reaching the hearts of the hardcore laser taggers I know (not to mention seeing no real signs of their products leaping off store shelves), these systems haven't come close to breathing any new life into the sport I know and love as Laser Tag. I hope someone comes out with something to show 'em how it's done.
