Well your poll covers a good bit.
2011 Enertia seems a no brainer as Brammo knows that the public loves the Enerita, but wants a bit more from it.
2011 Empulse final specs is also a good bet as we know it will have different bars and pegs...and likely a modified seat and "tank".
2011 Anti-Scooter...this is less likely just yet, but makes perfect sense...another good city ride and better for shorter people who don't fit the Empulse or Enertia.
Having all three will really open up sales for Brammo...well that and having a presence outside of the Far Left coast
As Brammofan mentions in his latest blog post, the Enertia and Anti Scooter and even Empulse would sell tons in NYC...and Baltimore and Philly and Miami and Houston and heck every major city needs to sell boat loads of EV powercycles...perfect city machines with no gas or emissions...
