While Blackberry 10 has been delayed until next year, RIM isn’t sitting out on the sidelines entirely this fall. The company is planning on releasing a 4G LTE version its Blackberry Playbook sometime in Q4 of 2012.

This is all according to a leaked roadmap as seen below that Blackberry OS obtained.

Here are RIM’s plans for 2012-2013:

• 4G LTE Playbook, dubbed “Winchester 2”, set for Q4 2012
• BlackBerry 10 London/Nevada – Q1, 2013
• BlackBerry 10 Upgrade for PlayBook – Q1/Q2, 2013
• BlackBerry device codenamed “Nashville” – Q2/Q3, 2013
• BlackBerry 10 inch PlayBook “Blackforest” – Q3, 2013
• BlackBerry device codenamed “Naples” – Q3/Q4, 2013

BlackberryOS, notes RIM is planning on launching Blackberry 10 in Europe first because European markets ”have been better receptive to Blackberry than the doom-and-gloom of the American markets”.
