Haha nice analogy. Well the Alpha mount is not the most adaptable, certainly true. Expensive depends on what is in the box though really, and I think it will be explosive. Not literally I hope!
GH3 and A99 have major possibility of providing far better image quality and all-round usability / featureset than any of the current favourites, be it FS100, Blackmagic Cinema Camera or 5D.
Some on Twitter have been underestimating the significance of product planning too. They say it is just a rumour and proof is in the pudding. But for me the pudding is mostly in the cooking and the 5D Mark III was cooked up for photography not video. The chef in this instance is a videographer.
That news alone is enough to have me very excited for the A99.
