Preview at WWDC likely in June, followed by September launch.
New Apple TV Teardown Provides Closer Look at A8 Chip, Larger Heat Sink and Siri Remote
Under the hood, the new Apple TV features a dual-core, 64-bit Apple A8 chip with 2GB of SK Hynix LPDDR3 SDRAM, custom Apple memory controller, SK Hynix NAND flash storage, Universal Scientific Industrial Wi-Fi module and SMSC USB 2.0 to 10/100 Ethernet controller.

The new Apple TV also has a larger heat sink, which is likely a contributing factor to the set-top box's taller form factor. The redesigned power supply is rated at 12V at 0.917A, compared to the third-generation Apple TV's rating of 3.4V at 1.75A. The heat sink is situated above the heat-sensitive logic board.
The teardown of the Siri Remote reveals a ST Microelectronics low-power ARM Cortex-M3 MCU, Qualcomm CSR1010 Bluetooth radio, Texas Instruments low-power digital signal processor, the same Broadcom touch screen controller used in the iPhone 5s/5c and iPad Air, 410 mAh battery and a few other chips.
iFixit gave the new Apple TV a strong repairability score of 8 out of 10, with ten being the easiest to repair, because it has only a few major components, a replaceable power supply and standard Torx screws. It also found the Siri Remote has a wide gap, making it easy to pry apart for repairs.
