Well, I didn't think this post from nearly 10 years ago would spark a weight debate again.

The main interest for me was the lack of prediction of what HAS come about (Electrics), as opposed to what hasn't came about.

Personally, in another 10 years time I'd expect nearly 100% Electric, with sensored motors and contra-drives as standard fare, and lots more aerodynamic gadgets poking out into the breeze ala F3P. Will "roaches" survive another 10 years?

As for size and weight, that depends on who does the lobbying and how hard?
