Ack.
This year we'll see a 32 GB iPhone 3G and maybe a 64 GB iPod touch and OS 2.3 - maybe even 2.4 and 2.5 (in November) with some additional features like 2.1 ==> 2.2 (maybe copy & paste, modem, video). Nothing more. Sorry folks. You'll get enough amazing stuff in App Store. Jailbreakers will enjoy the upcoming bluetooth hack and additional hardware accessoires will be built only because of this hack.
Next year (2010) sooner or later (at least in June) Apple will present a new generation, perfect tested and stable iPhone with multicore CPU, multicore GPU, even more storage, brand new OS/FW 3.0 with lots of new awesome features like multitrack recording (audio), video editing, backgrounding (multitasking) etc.
Outside TV broadcasting in your shirt's pocket, maybe with high definition. I can't await it but it will be there. Just need to be patient.
Just my two Eurocents.
