Shawn sent out an email to those that had preordered. Here it is.
"Hello,
The US MS3 shipment was released from customs today. Apparently it was detained until further customs information from Japan could be acquired. However, two cases did make it through, probably was sent separately from the bulk of the main shipment.

A confirmation was received numerous times for the gold warning label application. Regardless, it appears that both the Japanese re-release, & the new English release lack this warning label. The rest of the material is what you would expect from SNK, nothing is substandard, or radically changed.
The two cases (24 copies) will be shipped to customers in the order that the preorders were received. Also, Zupapa posters & flyers were received today, but no sign of the Sengoku 3 posters at this time. An email containing your delivery confirmation or tracking # will follow soon."
There you go. Makes no difference to me. Some English games have had the sticker in the past, others haven't. No biggie. Just the way it was released, nothing more, nothing less.
