Well-known former Microsoft technical evangelist and blogger Robert Scoble expects Apple to reveal many products at WWDC next week, as information from UK Mac sales channels suggests some products are in limited availability.

In a discussion, in which he warns that Microsoft's new operating system, Vista, isn't "anywhere near ready", Scoble warns that if Vista ships in October he'll refuse to install it until it is revised.

He compares Microsoft with Apple, and states: "Speaking of Apple, they are readying a dizzying amount of new products. I wish I could camp out at an Apple store during the World Wide Developer Conference on August 7. I wish I could say more, but that'd get me sued by Steve Jobs and I don't need that kind of heck right now."

Second-guessing Apple in advance of any of its key events has become an infatuation for many. History shows that speculation on Apple's activities may often be wrong, and Scoble could be incorrect in this case.

However, new information on availability from UK sales channels shows limited availability of the top-end Mac mini, the 1.83GHz 17-inch iMac and the Power Mac G5.

While most other Apple products remain in stock, it appears that - in the UK at least - iPod stocks are running down, with 30GB black 5G iPods with video the most available build at present. (In that just under half of outstanding orders for this product will be shipped in the next three weeks).

Apple isn't expected to reveal any new iPods until September at the earliest, but with Apple Expo Paris approaching and next week's WWDC, will the company want to lose the potential publicity any such announcement would create?
