This week we heard about Apple releasing its updated Mac OS X Lion operating system with some 250 new features. Now, according to 9to5 Mac, Apple is launching this week Lion powered new MacBook Airs and Mac Pros.

The computer giant is releasing both ultra-thin MacBook Air notebooks and a new line of Macs for professionals. In fact, 9to5 Mac website also provides product numbers for this new line of notebooks and desktops.

As per this report, Apple will be releasing four new MacBook Air models. This includes two 11-inch notebooks and two 13-inch units. Both screen sizes will come in entry level and upgraded configurations, wrote 9to5 Mac. The website also talked about built-to-order options (BTO).

The 9to5Mac reporter is also expecting some RAM and processor upgrades, along with speedy Sandy Bridge processors and Thunderbolt I/Os.  While there are quite a few hardware upgrades, the 9to5Mac source is not expecting any noticeable exterior changes.

According to 9to5Mac, though the rumor was that new Mac Pros were coming July end, it now looks like Apple will be releasing them to the market this week. Speaking of external design, the new Mac Pros will offer a re-designed enclosure that is both narrower and rack-mountable. A faster, 16-core model is a possibility and thunderbolt is an obvious addition, wrote 9to5 Mac reporter Mark Gurman. Gurman also expects a new Mac Pro server model to debut.

As previously reported by 9to5Mac, these new Macs will be Apple’s first to ship with the Mac OS X Lion pre-installed. Meanwhile, media reports indicate that Apple is expected to release OS X Lion through the Mac App Store this week.  In essence, Apple’s all three new products are releasing this week.
