Scalia, Thomas, Kennedy are rather anti-states rights (which not to get on a rant should be called "states powers" because states don't have any rights).
Still I think Scalia while pointing out the inherent flaw in Cruikshank has already tipped his hand. Cruikshank case (1876) declared neither the 1st nor the 2nd is incorporated against the states. The 1st has been reversed due to 14th it seems shaky legal ground at best to say the 1st has been incorporated via the 14th but somehow the 2nd hasn't and Cruikshank stands but only stand on the portion related to the 2nd.
http://en.wikipedia.org/wiki/United_States_v._CruikshankPrecedents have lasting consequences. The case could be used as precedent in a totally unrelated topic decades from now. For example say the federal courts find marriage to be a fundamental right. An individual is a state not allowing same sex marriage could sue using the "gun case" as precedent and find the state law unconstitutional due to its ban on a fundamental right. To think the case's lasting impact is limited to "gunz" is silly. Justices are always looking at the bigger indirect issue. The reverse is also true a failure to incorporate (depending on wording of decision) could be used as precedent for those who wish to allow state to infringe upon a right the federal courts have found to be protected.
It would be far easier for marriage equality for example to win at federal level (where judges tend to be more progressive) and have that decision applied to all states then try and get marriage equality in say Texas or Georgia.
Both "sides" have some serious philosophical issues.
The one who are generally speaking "pro-incorporation" are the ones who ruled against Heller.
The ones who are generally speaking "anti-incorporation" are the ones who ruled in favor of Heller.
Maybe I am the only one who sees the irony in it. I also don't think Kennedy vote is locked up. The issue will come down to "fundamental rights".
