What you say is true, Vesa is indeed working on a new car.
What we noticed last year is, that with loosing a heavy NiMH battery, you've also lost pressure on the rear tires, which means loosing reargrip (also has to do something with chassis roll). The cars got much more agressive then the where with NiMH's.
Last year I've only raced my battery forward on every track, and even put my elec's more out front. Widend my car on every track with 2mm on each side. Also when looking to front tyre sauce. with NiMH's I would sauce the tyres sometimes for almost 50%, With lipo, putting on 30% was much, and most of the time I've put on less.
All of this is just because with lipo's te car's are having much more "steering" then with NiMH's. That's why the lipo conversions of Asso, SpeedMerch, and CEFX got longer and wider, to make the car drive a bit more easy.

I don't think it only has to do with moving weight forward. I've just converted my RC12R5.1 to this battery conversion, and the electronics aren't so "wide" as the were with the old battery position. This would mean the car will chang's from left to right much faster. Which will make it quicker, true chicanes, but also carry more cornerspeed true the corners.
The cell isn't central but with the picture displayed my car is perfectly balanced with out any lead (old pic):
The only thing I'm wondering is why all the guys put the battery plugs out front. This will put the "heavy side" of the battery on the rear, which will make it more agressive, then putting the plugs on the back. But I'll try and test this tonight maybe.
