I have two issues with some of the comments on this thread. Obviously there's no one here in marketing

"If it ain't broke, don't fix it". Right. So if AE remain undefeated for a decade we won't see any progress? We don't think that other variables will affect the ever-changing requirements of a car (eg as someone has posted, taller body for brushless ESC etc)?

Secondly, companies (RC or otherwise) don't always bring out a new model just to 'fix' something that's 'broke'. They do it to make sales. If everyone is happy with their B4 and then AE release a B5, you think no one will replace their B4 because there's nothing wrong with theirs? There is a whole market of people (me included) that like to have the latest, even if there is no tangeable improvement!

I'm a good example. I've been out of 2WD class for a while. I recently decided to buy a used one. I went with a XXX-CR because I decided that if AE bring out a B5, then that would most likely be the best choice and the CR would be easier to sell than an outgoing B4 model - that and I don't think there's much in it between the two cars right now (but that's a whole other discussion!).

So just some food for thought guys, interested to hear other perspectives.
