Upcoming Software Update - What fixes?

Will the upcoming software update (mentioned in a reply to one of these threads) fix:

1) The image issues many are experiencing (washed out)?  It can be addressed in chrome, but that doesn't help other apps such as Amazon or the Verizon apps.

2) Audio quiet when headphones plugged in before audio starts, but normal if plugged in after sound starts?

3) Tablet won't power on after sleep?

4) Excessive battery drian while tablet is powered off?  Or in sleep?

5) Screen casting lag (unusable)?

6) The really ugly emoji characters?

7) Inability to organize or group app icons?

What other issues will it fix?  Improvements?

When will it be released (with all these issues I need to decide if I wait for an update or just return the device)?
