The speculation is that 10.6 will be out by next year so its well within the time frame. I don't see why I shouldn't receive the "full luxury treatment" just because I buy a refurb. Every customer should be entitled to the same Apple experience and that includes the traditional long support of hardware.
Did you even read my post? Yes, it's well within the time-frame for 10.6, and I've consistently said that I think it would be unwise and somewhat unfair for 10.6 to drop PPC support.
The reason you shouldn't receive the 'full luxury treatment' is two-fold. One, you make up a very small percentage of customers and two, refurb products are likely to be out-dated compared to the main product range, hence why they're sold in the refurb store rather than be salvaged and repackaged as new.
