Not really.

First of all, I think there's a good chance they will release it. If they don't, it will likely be due to the fact that they're unable to, rather than unwilling.

But even if Disney makes the decision to never release the unaltered trilogy, it has nothing to do with the people making VII, and it remains separate from my desire to see the new film. So far, I'm interested. That may change over the next year, who knows.

I'm not sure if you're proposing an actual boycott. The film is going to be massively successful, financially, either way. I can understand not buying a 'complete' blu ray set that includes the Special Editions, though. If you're interested in boycotts, I recall a very silly thread where people proposed buying and returning blu rays. Worth reading for a laugh.
