Images of what are claimed to be iPad 3 components have surfaced online, showing few changes from the current iPad 2 design.

The MIC Gadget blog has published photographs of what are claimed to be the front glass panel and rear shell of the next-generation iPad, as well as a video featuring the components (below).

There are also photographs of the Home button - which some had speculated would be missing from the iPad 3 when Apple's official invitations were sent out - adding weight to separate reports from last week that the Home button would still be present.

MIC Gadget says that the iPad 3 will come in three capacities - 16GB, 32GB and 64GB - despite reports from Taiwan last week that only mentioned the 16GB and 32GB models. Interestingly, the report claims that the prices will be the same as the current iPad 2 prices, and there will be no 4G/LTE capabilities.

Meanwhile, a report in Ars Technica claims that devices running iOS 6.0 have been visiting its website, logging on from within a block of IP addresses known to belong to Apple.

The data also shows that a device with a resolution of 2048 x 1536, which is the expected resolution of the iPad 3's retina display, has also been visiting the website. However, as Ars Technica has since clarified, the device with the 2048 x 1536 resolution isn't necessarily running iOS 6.

Apple Insider has noted that Apple is decorating San Francisco's Yerba Buena Center for the Arts with a large, colourful banner in preparation for Wednesday's event.
