Is this another whole new iPhone design?
We expect some of the usual updates -- faster, more memory, new chip, maybe some new hardware features -- and a new design for the iPhone 5.
While the iPhone 4 is still an attractive phone, and is still selling, it will be a year old this June. That's a long time in the smartphone industry, where new phones are constantly coming out. So we don't expect another iPhone 3GS-like "update" from Apple ever again, where it keeps the same phone case design from one year to the next but only upgrades the guts.
This supposed leaked image could be it -- sure looks like the iPad 2 -- or could be a fake. But either way, we expect a new design.
The critics have shut up about Apple's iPhone 4 design, and "Antennagate" didn't seem to have any effect on sales. So we wouldn't be surprised to see the iPhone 4 stick around as Apple's cheaper iPhone model. But we expect at least some moderate updates this year to the high-end model.
