yea, from a consumer standpoint its incredibly annoying (thats why we have the whole magic lantern and voiding warranty race) but from a marketing standpoint it makes a lot of sense, since people would be forced to buy a higher model.
its the exact same model apple follows by not allowing older machines to run lion/mountain lion or getting siri on their iPhone 4/3Gs
Are you insane? Technology changes. Sorry they had no idea how to write the software to make it work that fast. Guess what... almost ALL software isn't utilizing the hardware available. Hardware is by far ahead of software in every aspect it is outstanding. The 5dII was "capable" of 24fps when released but the software wasn't ready yet. Was the biggest leap in DSLR's "crippled" because the software wasn't up to snuff yet? Find something else to be outraged about.
