RIM says its PlayBook will be out in time -

RIM's PlayBook tablet PC is to be launched in March or April, despite rumours of a delay.

That's according to the WSJ, which has been getting up close and personal with Jim Balsillie at MWC.

In an interview with the RIM co-chief exec, the paper reported that the "tablet's development [was] proceeding as anticipated."

And it seems RIM is keen to get journos lusting over the device, showing off a prototype of the tablet that runs on high-speed, fourth-generation telephony networks.

Mr Balsillie also moved to quash rumours that the PlayBook had poor battery life compared to other devices which are currently on the market. Unlike Apple's iPad , which targets those who have a little bit of wonga, it seems that the PlayBook may be throwing itself at a less showy audience, with Mr Balsillie claiming that the device should come with a sub $500 price tag. The company also believes that this may be lower depending on the network users choose.

Currently only Sprint is on board, but it looks like AT&T and Verizon Wireless may also join the relationship. And there could be many more global deals with many of RIMs  580 carrier partners in 165 countries.  Carriers want it.

However, when it comes to application relationships, Mr Balsillie seemed to clam up as quickly as some wallets on Valentines Day, refusing to comment on whether the device would support apps for Android. There might be some love lost there.
