It's just that I have ordered the m17 with the 880m but am aware that there is a superior GPU available. The 980m is something I want to get eventually and I wanted to make certain that it is an option. Another question I have is when they release a refresh of the m17 sometime this year, will it be the same looking as it is now? Just with upgraded components?
No, the Alienware laptops will not be of the same design. In fact, they have already changed. Dell just announced at the 2015 CES that they are in fact changing the design of the Alienware laptops. Starting now, the Alienware 15 and Alienware 17 have been redesigned and are available for sale right now. Note that the Alienware 14 is no longer available and the new Alienware 13 is shown along with the newly designed Alienware 15 and 17:

The new design is thinner and lighter. However, what will not change is the fact that the graphics cards will still be upgradable using the existing Mobile PCI Express Module (MXM) slot. FYI, the Alienware 18 has two MXM slots.
The most important change IMHO is the fact that the new Alienware 15 and 17 (and eventually 18) is that they are now compatible with the new Alienware Graphics Amplifier. This was made possible due to the redesign of the laptop. The Graphics Amplifier port is located at the center on the back of the laptop (just like on the Alienware 13).
