Rock Band 2 standalone instruments set to ship next week

Previously, the ship dates for Rock Band 2 instruments ranged from "sometime within the next few months" to "sometime." Now, however, we're hearing that the standalone wireless drums ($90) and guitar ($70) will begin to ship out next week (at least for the Xbox 360). Additionally, Mad Catz's Fender P-Bass wireless guitar controller ($70) and the wired ION Drum Rocker set ($300) should clutter up floor space around the same time.
