Well going by recent posts on esato, Honamis camera will have a sensor size of 1/1.6". For comparisons sake, here is a graphic comparing the Homani sensor size on the left vs. the Xperia Z sensor size which is 1/3.06"
REALLY hoping this is true as it'll be the largest sensor in a phone save for the Pureview 808 and its 1/1.2" sensor. In comparison though, Honami should be far thinner, so that's all good.
Another reliable poster from esato has mentioned no xenon flash for Honami though, which makes me sad... was REALLY hoping to finally get that on a phone. Hope he's either incorrect, or that there will be some variant with it.
There does seem to be a fair bit of confusion over just how many high end phones Sony are planning. As zomg pointed out, Sony has really locked down the leaks. I'm just hoping we don't have to wait all the way until the official announcements
