from the looks of things you won't be able to upgrade the ram or the flash storage. It looks like everything is integrated with the motherboard
new speakers though
'Dual Adaptive Microphones' sounds interesting
It seems to go even further than that, the SSD is proprietary and currently irreplaceable, the battery is glued in and is now a $200 upgrade and the RAM is soldered to the logic board, along with a screen that is fused to the frame.
The old design is definitely looking more attractive to the pro user..
