Who wrote that app?
Canon? Or just some guy who works elsewhere?
If canon wrote it, then ok, it's more believable.
But still, 4 in Chinese / Japanese is 四, 'sì' in Mandarin. Death is 死, 'sǐ'.
They've just proven that there will be no G13 or G14 (14, 十四, 'shī sì', sounds like 尸死, 'shī sǐ', 'dead corpse', 逝 shì means die, 弑 shì means 'murder a superior' (yes, I just went through my dictionary and found them)).
In short, they're a superstitious bunch (or at least, they acknowledge that their customers are), there will never be an EOS 4D.
I'm guessing that some other guy wrote the app, and it's a typo, he really meant to write '3D', which will be the kick-ass high-MP camera we're all waiting for
