Not really. People wouldn't stop complaining about support so they released a test version with a method they have working. It's a beta release. NOT FINAL. Beta means test. It is still in the test phase. If they released this saying "This is the final release. Enjoy!" that'd be a lie. They released what they have currently using the best, most stable exploit they have currently. Yes, it requires extra hardware but their statement about not requiring extra hardware is meant for the final release. Anyone who thinks otherwise is an idiot.
So do you believe that they have a method working behind the scenes that does not require anything beyond the N3DS and the GW cart?
At this point I believe they have one method, OoT. I haven't seen anything else to indicate they have or will have a method that only requires the GW cart.
