Having owned or tinkered with virtually every TC on the market at some stage or another over the last 10 years I have a fair bit of knowledge about TC setup and design. I can assure you for a fact that this chassis is a MAJOR change from the T2 platform which I also have owned. I haven't been a big fan of xray since I owned a few of them but I am sure this car is a huge change and has much potential. If you don't understand why then you may explaining it would not help. I suggest you just try one when it comes out.
BTW I have been bagging XRAY for years so I am hardly biased.
