So many Nokia Ace/Lumia 900 rumors, that it’s hard to keep track. We already knew that the handset was coming, but specific info on when that might happen hasn’t emerged so far. New reports, however, suggest that elusive Nokia Lumia 900 will be revealed next month at CES 2012 in Las Vegas (which will be present for) and will launch on March 18th on AT&T. The Nokia Ace will launch with OS Tango which is said to have LTE support. The Nokia Ace is said to feature a 4.3-inch display, and a 1.4 GHz processor.

On a side note, Nokia Lumia 710 will ship on Verizon Wireless without LTE in April 2012. This device is coming to T-mobile first on January 11th.

We have to wait to CES and will find out more on what Nokia has in store with Lumia series.
