572 and 577XP, both grown up versions of the 562XP, with auto-tune. They will both be 75cc, but the 572 won't have the stuffers and will be de-tuned, with some sort of flow restrictors in the removable transfer covers that are easily ground out.They will be out sometime in early 2013 and will be quickly recalled with some "unknown" issue (actually bearing problems). They will be re-released about 2.5 months later.
As a side note, Husqvarna will change there color scheme from the new orange with dark metallic gray accents, to a candy apple/pearl orange with teal highlights and a hot pink racing stripe and graphics on the bar that say "Professional Gasoline Power Saw". The overall shape of these saws will resemble a Japanese Motorcycle complete with a faux speedometer and tach on the airfilter. I am told there will be liberal use of flames and lightning bolts in the graphics as well.
