As others have mentioned you'll get a quality built bino. As a general rule I find the alpha stuff easy(er) on the eyes.
Also, Swaro will refurbish them generally for free.
Swaro will upgrade them for a price--usually $300-$500. That includes Swarovision,etc.

You are correct that Swarovski will upgrade binoculars, to newer specs. That mainly includes the older SLC series.
Not the Swarovision, they don't need any changes, since the optics have not changed, since introduction.
