Is this something?
Similar to what James Ben found on the Citi Premier thread, regarding a app link without the 18 month language:

I got to this application by checking for pre-qualified offers. I wasn't pre-qualified, but this was among the several cards that were listed. I also saw the app for the Premier that James Ben saw.
There is no landing page, but the description in the pre-qual page says 75000 Hilton HHonors points after spending $2,000 in 3 months. I see no mention of 18 months anywhere.
