We've gotten some definitive answers, with still a couple left to be addressed, but I thought it would be good to start a separate topic for the folks that have the Gen2 flash. Most that have posted they're getting it have either JUST gotten it back, or are en route to/from ECUnleashed in CA.
The ECUnleashed flash is agnostic as far as NA/UK/SA origin. The same flash performs the same modifications.
Here's what was described as in the previous post:

What exactly does the Gen2 reflash update change?

What exactly does the Gen2 reflash update change?
- Significant improvements to the throttle response in "S" mode maps
- Greater fuel efficiency in "S" mode maps
- "T" mode mapping remains stock but we made slight adjustments to the AFR (Air/Fuel Ratio) in 5th and 6th gear producing a value of 13:1 as opposed to 12.7:1(factory)
- Better advance maps over both cylinders 1 and 2 - referring to ignition timing changes. Better, in this case, meaning smoother ignition maps for both cylinders.
- Fully compensated for the closed loop routine below 5k rpm
- Removal of the top speed limiter
- Removal of the factory timing retardation
- Removal of the factory throttle restrictions
- Increased rev limit by 500rpm- no cost option
- Increase idle up to 1250- no cost option
- Less engine braking and improved decel maps
- Improved throttle control
- Eliminate the factory injector cut off
- Eliminate dash error codes
- and all of the benefits from the gen 2 flash as well.
- The stock O2 sensors are still utilized if they are retained. You can either leave them connected as is (recommended if you don't have a PCV + AT as the ECU will still trim fuel accordingly), disconnect the connection under the right hand fairing, or remove the sensors all together (& clean up some wiring in the process) and plug them up in the stock headers SOURCE: http://www.r1-forum.com/forums/showthread.php?t=336803 2ND Source - a lot of other NA S10's are running without O2 sensors, but have a PCV + AT.
- Is there a need/benefit to having a Power Commander/Autotune? The answer is no and yes. It's no in that the ECU is flashed for fuel based on if you have a slipon or full exhaust. However, it's a generic map and not a custom map for your bike. On some bikes it may be dead on and on others it may be a bit off. However, you would need to remap your fuel controller after you have your ECU flashed. If you have the AutoTune this can be done by you, however if you don't you should get a custom dyno tune as you will need a new map to adjust for all the changes that ECUnleashed has made with fueling.

- If you don't have an PCV w/ Autotune, you must get a new PCV tune done on a dyno, or zero out the PC V AFR map and let the ECU handle fueling completely. Retaining the PCV + AT allows you to fine-tune fueling if installed.
