They will burn oil. There's a pill for that. The spring on the doohickey needs replaced. There's a pill for that too. There will never be enough pills for lying or ignorance which is a symptom your dealership is displaying.
Your evidence for this statement????? I have a 2010 with close to 5k on the clock. It has not burned oil yet. The 2008 and early 2009 models had a higher likelihood of being oil burners according to all I have read. Yet, I doubt all of those were oil burners. So no, it is not a foregone conclusion that a 2011 will burn oil.
The doohickey is better in itself than those on the first generation klrs. The spring may still be somewhat lacking on many bikes.
Let's look worst case. If it burns a quart every 1000 miles, it costs an extra $3.50 per 1000 miles. If you are worried about the doo, the kit with the doo, spring, and the specialty tool needed is $120 or so. The 685 kit that cures oil burning and adds displacement is less than $500. As a matter of fact, I believe doo, thermobob, and 685 can all be obtained for less than $500.
My opinion is that there may be too many following certain break in advice over on another forum. That advice is something along the lines of rag the heck out of it from the get go. I think any advice of that sort is bad. Not allowing rings to seat correctly WILL cause an oil burner.
