RIM has not given up on the PlayBook tablet, and the next models have already been submitted to the FCC. The new PlayBook models will deliver a 3G model with HSPA+ and an LTE compatible model that sources tell us should hit dealer shelves around late May or early June.

The new PlayBook models look to be AT&T LTE compatible as well as offering support for AT&T’s 3G/HSPA+.  The unit will be powered by a 1.5GHz processor, which is believed to be dual core, and it will offer NFC support.

Of course, the new units will use Version 2 of the PlayBook OS, which should help gain it traction and expand its user base. Still, it is unknown if this will make the kind of impact necessary to push RIM into the position to be a real player within the tablet market. With the recent launch of the new Apple iPad HD, it is going to be tough sledding for RIM, we suspect.
