"A recent poll shows that 41% of current smartphone owners are considering the iPhone 5 for their next device--even though the respondents know nothing about the device yet," Zeman writes.
So, what are you likely to see at Tuesday's announcement? Zeman's betting on a larger display and faster processor, for starters.
As for the design, Zeman expects that this iPhone will be thinner than the iPhone 4, use a tear-drop shape, and skip the glass back that made phone-droppers even more nervous. As the Wall Street Journal wrote on Monday, it's getting harder for Apple to find ways to be truly "out there" with design, as its rivals catch up.
Watch these three other tidbits, generating their fair share of speculation:
-- A cheaper iPhone 4? Gizmodo posted some photos from a Foxconn factory in Brazil over the weekend that supposedly show a less expensive iPhone 4 in the works.
-- Voice navigation? Macworld is downplaying the notion of multiple phones being announced tomorrow but it is talking about the possibility of real voice commands.
-- R.I.P. iPod? Finally, Ars Technica is not the only outlet speculating that tomorrow may be the end of the line for your old iPod.
