So I saw on the new releases (pg. 2) there is a new 4800 Lipo Saddle Pack. I think that would fit very well into a new shaft drive 4wd 1/10 buggy. Hmmmm. But the "New Losi RTR 04.16.09" link on Losi's site leads me to believe it won't be a 4wd buggy.
In the picture you can see the X-2000/X-3000 tread pattern. So seems to 1/10 scale something. I kind of think it will be a 4wd 1/10 buggy but it will be more along the lines of the HPI Brama 10B. So that's my guess. We'll find out Thursday for sure I guess.
