New iBooks next week?

A German Mac news site, MacGadget, seems pretty confident that Apple will be releasing new iBooks this coming Tuesday. If this were only posted on a rumors site I wouldn't pay it too much attention, but I have a good hunch that it's accurate. I guess we'll find out on Tuesday!

Here's a loose translation from their site.

(16:20 o'clock) New iBooks on Tuesday.  Apple will announce on coming Tuesday a revised iBook G4 product line.  Apart from the usual technical improvements, speed bumps and price reductions for all three iBook G4 models are expected. The improved iBooks are alreadyen route to dealers and distributors.
