I like everything about Nitro except for the fumes...they hate me and make me unable to breath very well. I love the whole concept of tuning though, and how efficient to be for fuel/pit strategies and long races.
For Tekno, and all of us, I hope the Nitro does as well as the EB has so they continue to get great return on their R&D investment and can keep doing more of it. I'm definitely most excited by the concept of a Tekno EB410. With the nitro being shown though, I would be surprised to see an EB410 before an 8th scale truggy, unless they're developing multiple cars at once.
