Unless something has changed or come up internally...
2.0 will be out before or on October 7th, according to the (albeit
google translated) press release regarding the glacial white PS4 in Japan.
I do remember hearing/reading about 2.0 coming out Sept 26 during the TGS presser but never found any other source or instance to back this up...
Also to those bitching about DLNA support and suspend and resume support....
DLNA is a lot more involved than just slapping hooks into system to allow functionality, if Sony wants to duplicate what they did with DLNA on PS3 a lot of red tape is involved as they included DTCP-IP support which is a proprietary, licensed system that allows the playback of Copy-Once channels that are streamed from devices like HDHomerun Prime.
A lot of devices that DLNA certified do not support the protocol.
The suspend/resume is also a not an easy programming task, FreeBSD and NetBSD (the OS the PS4 system software is run on) doesn't officially support (it's implemented but it's about as stable as Ford Pinto in terms reliability and compatibility) suspending and resume OS.
Add the fact that the PS4 uses a unique memory pool that's not used on most systems and also has a separate processor with its own architecture and memory (ARM-based with 256 MB of DDR3 SDRAM) is something that isn't implemented in a few weeks but months as it's system function that has to account for the bulk of the contents in memory.
