Update: It's not speculative anymore. Google finally released the new logo and cleaner home page for most users as of this morning.
The latest version of Chrome Beta for Android features a new design for Google's new flattened logo.
The new version is cleaner, which is a much needed attribute when using a serif typeface and many colors.
It's worth noting that a similar flag logo for Google+ has been present on Brands of the World since March 2011 with slightly different hues of colors.
Also, check out the Google logo designed by Stefano Perrone.
