John Gruber of Daring Fireball fame has cast his prediction in to the pot as to what we’ll see at WWDC.

Gruber is usual spot on with his predictions and this time he’s saying that the next gen iPhone will be called, or at least code named “iPhone 3GS.” He’s unsure of what the “S” stands for but knows that it will branded on to a new, faster model.

“I expect Apple to announce updated iPhones with significantly faster processors, twice the RAM, and twice the storage. I expected prices to remain the same as the current lineup: $199/299 for 16/32 GB, respectively. The video camera is going to be a major selling point.”

It will be interesting to see what the third generation iPhone’s final name is. The current iPhone 3G could become the $99 model analysts have been hoping for while the more expensive and up-to-date version could be dubbed “iPhone Video” according to some rumors.
