It's more likely than you think! According to a Russian MtG site, there is a card in M10 with the art seen to your left. They are calling the card Lightning Bolt, but there is no further confirmation as of right now. If this is indeed the case, it would seem Ball Lightning gets yet another boost. Bolt was THE iconic red burn spell back in "the day", and Shock and Incinerate have never really had the same appeal. In Standard, many things die to both Shock and Bolt so I don't see it being a big deal removal-wise. As far as straight burn goes, having Bloodbraid Elf, Ball Lightning, Bolt, Boggart Ram-Gang and maybe Flame Javelin (if you're feeling lucky) in the same deck will mean for some heinously aggressive Red Decks. I personally can't wait!
