Apple is widely expected to unveil new models of its iPad and iPad mini at a major event on Tuesday. Here’s a look at what analysts and tech blogs are anticipating in the new models.

What’s expected: On the iPad front, Apple is expected to announce two new models — updates to the full-sized iPad and the iPad mini. In general, analysts and tech bloggers expect the new iPads to have a faster processing chip — the A7 chip that’s now in the iPhone 5s.

Some design changes are also on the list. The full-sized iPad is expected to now look more like its little brother — lighter and thinner. Mac Rumors also reported that updates to the iPad’s front and rear-facing cameras are expected to get some kind of upgrade.

Touch ID? Some analysts predict that the new iPad models will offer the fingerprint recognition scanner and software that Apple recently debuted on the iPhone 5s. But analyst Ming-chi Kuo, who’s had a good run of successful Apple product predictions this year, said in a recent note that he does not believe the new iPad will include the feature, 9 to 5 Mac reported. Kuo, the report said, also does not expect that the iPad will be released in gold, the new color offered for the iPhone 5s this year.

Retina iPad mini delays? Since the iPad mini first launched a year ago, many have been expecting Apple to introduce a retina-display version of the smaller tablet. That speculation is still high, but Reuters recently reported that there may be delays for a sharper version of the iPad mini because of supplier problems in getting the screens for the tablet. The report indicated that, if the displays were in short supply, Apple may not be able to fully roll out a higher-resolution iPad mini in time for the holidays. That would place it at a disadvantage against new models from competitors such as the Amazon Kindle Fire HDX and the Google Nexus 7.
