It's definitely getting warmer. (No pun intended.)
And let me clarify that I have NOT seen Hasbro packaging, just Lucas Licensing's images from their style guide. This is the same guide every Star Wars licensee will use to package Episode III and other saga merchandise.
For those interested, the collector's packaging remains relatively unchanged. The upscale branding used by licensees like Master Replicas will retain its simple gold on black trade dress. Very classy.
