Is Blue Arrow on Google Homepage Permanently or Temporary ?

Many people are asking about Blue Arrow on Homepage of Google. Some people are asking will this blue arrow on Google home page is permanently or temporary.

I think its a temporary and I searched it on Google and I got answer. According to a Google Employee which reply to a forum thread that

The blue arrow will not appear on the Google homepage permanently. If you click on Web in the top bar above the homepage, you should still see the Google homepage. If you click +You, you should be directed to the Google+ sign-up page.

Please let me know if you're experiencing something different.

I already post about this blue arrow in my previous post i.e. How Google is Promoting Google + ?
