Appears to be just a Smart Arrow Messenger board in an Edge Plus housing; those aren't a new thing. However I don't remember there even being a blue one....just red or amber.
It's cool but I think its' a waste of money too. Going off '08 list prices (this thing isn't even listed in the current book), an amber one was $1700 (blue is probably more), control heads each are $400-$500, programming kits are like $400+
This version apparently has a way to control the messages 'on the fly'. In the older ones you had police, fire, or DOT libraries & had to use those messages unless you programmed in special ones.
If I want to know whats' going on in NYC that bad, I'll turn the TV on....not look for an NYPD car that might have a message board....
