9 to 5 Mac reports that a number of Apple resellers have been notified that iPad supplies are currently "constrained" and that there is no estimate on when they may become available. The development is not much of a surprise, considering that Apple has been widely rumored to be introducing the next-generation iPad at a media event on Wednesday, just two days from now.

The fact that supplies are already drying up does hint, however, that we may see the new iPad go on sale sooner rather than later. That would match up with a report from AppleInsider late last week claiming that customers should be able to expect "near immediate availability" of the new iPad.
