The iPhone and iPad rumor mill continues to heat up.

Apple is reportedly prepping the iPhone 5S for a summer release, mostly likely in August, "sources familiar with the plans" told blog site iMore. The next iPhone would sport the same design as its predecessor but with a beefier processor and better camera.

People awaiting a new iPad could get some satisfaction as early as next month, according to the sources.

An "April-ish" launch for the next-generation iPads, most likely the iPad 5 and the iPad Mini 2, is seriously being considered by Apple. From that description, it hardly sounds like the date is written in stone, and even iMore admits it's not sure what to make of that.

The rumored release for the iPhone 5S may have credibility.

Other sources have chimed in with a late summer launch date, most notably KGI Securities' Ming-Chi Kuo, who projects that the new phone will be announced in June and reach the market in July.

But the iPad reports are on thin ground.

Apple is unlikely to release the iPad 5 so soon after the October release of the fourth-generation model and last March's debut of the third-gen edition. And the iPad Mini 2, which will reportedly sport a Retina Display, isn't likely to hit the market while Apple is still enjoying healthy sales of the current version.
