That's great timing for monster hunter players 
To be honest, the battery only occasionally is an issue for my gaming time, but I can see that issue growing bigger with monster hunter coming. I hated the bulky addon power juice pack, so I'm definitely interested in improving the internal battery without external changes. Weight, though, is important.
Oh and a cable isn't an option. I've got kids, a rabbit and a couch that definitely do not agree with cables hanging around my house. If the rabbit visits, kiss any nunchuk, classic controller or gamepad charger goodbye. Yes, even with lightning reflexes. Cost me 3 nunchucks and 2 classic controllers during the wii's lifetime lol
