The portals are offering some pretty sharp opportunities for advertising this year. Yahoo! is creating a Toy Buzz Index for the holidays that, if nothing else, will provide a good depiction of the latest ?hot toy of the season? phenomenon. I have the feeling it?s going to be a console-game Christmas. Microsoft?s Xbox 360 will be released ahead of Sony?s PlayStation 3 or Nintendo?s Revolution, both due out in 2006.
