Yes... we're re-launching Bigtrak this year... to answer the questions:
1: Yes, we sampled the sounds off the original as we felt they were a key part of it's charm.
2: It's about 7" long, 5" wide and 4" tall
3: No plans to do the trailer yet, new line of accessories include a digital camera and foam rocket launcher
4: There may be a new version later with wireless programming and other cool features... not in the Jr version though.
And yes, Zeon are making a collectors edition version of the original too... afaik they are launching about 6 weeks after we are though, not a month before.
We haven't even announced our launch date yet so you can't know they're a month before
