Beta days are coming!!! Don't expect to much, guess nothing in store for publishers, searchers, public and so forth. That announcement and only the announcement might be an anchor that they don't dive to fast to deep with their shares in the stockmarket. They are like buying time and start some brainstorming now. The rest is time and time and time and time...goes by...and nothing happens. They are not like adsense/adword programs and never will be, or else they would have acted on their recent mess with more responsibility and/or given some hints into this direction a long time before.
