This doesn't say anything. Really, why not apply a little logic here?
Do you really think if there is a new iPhone they're going to show a picture of it on a banner? Doesn't that wipe away the "one more thing" excitement?
Steve Jobs is a man who loves a show (much like his return is being tied into some major Apple announcement) so really? Do you think a new phone will be plastered on a banner for all to see prior to the WWDC?
I don't.
Anyone who did not think WWDC wasn't going to be about SL and 3.0 must be living under a rock.
