they missed the boat not making the new 650's higher amperage. Flame me if you like, it's just a giant vacuum was created once the sony's got scarce. I realize they are focused on safety first and foremost and not just tossing out a high rated battery for the sake of doing so, but it would seem there is still a hole that will need to be filled and whoever does it (provided they do it the right way) is going to profit.
