Apple probably will release an “iPad 2 Plus” device, which is a slightly upgraded iPad 2, according to FBR Capital analyst Craig Berger.

“There are some indications from the supply chain that Apple may look to introduce an 'iPad 2 Plus' device as they put out request for quotes from various component suppliers for this marginally different device,” Forbes quoted Berger as saying.

The iPad 2 is already very smart, but one flaw is about its screen and Apple wants to improve it. Berger noted that Apple might make the iPad’s display resolution from a current pixel density of 132 ppi to 250-300 ppi for the new “iPad 2 Plus”.

If iPad 2 Plus is really released, then production volumes of the 4th quarter in 2011 will decrease a little, Berger said. The reason is “screen constraints again arise as LG and/or Samsung would likely have difficulties ramping screen yield rates for these high resolution displays right out of the gate.”

Berger also mentioned that until there are more confirming data points from other supply chains, he can’t say for sure the “iPad 2 Plus” will be coming in 2011.
