When will we see IE12 ?

IE9 launched in March 2011.

IE10 RTM in August 2012 (somewhere around there)

IE11 RTM in August 2013

The next major update for Windows seems to be Threshold and that is espected in ~March 2015. So we basically have another ~year before an update to IE?

IE11 is GREAT for everything I need. It's fast, stable, smooth, battery efficient and it can sync with my phone and a tablet if I had one. The problem is that sometimes the browser STOPS keeping tabs from last session, which wrecks my nerves. A simple reset of the browser fixes the problem, but still. Also, if you load a page, sometimes IE won't take your input when clicking on another tab.

I need a more stable, flexible IE12. Also I really need the ability to pin tabs.
