Apple planning 5GB iPod mini

Given there are now a half-dozen other 5GB MP3 players out there competing with it now, this should probably come as zero surprise, but AppleInsider is reporting that Apple is going to bump the iPod mini up from 4GB to 5GB sometime early next year. Seems like a lock that they'd make the announcement at MacWorld next month, since it'd be a year since they first announced the iPod mini, but the one thing nobody knows for sure is if they'll introduce any new colors or not.
