How often does disney world release toy story themed merchandise?

The two verified sources supplied do not mention any schedule or pattern for the release of Toy Story themed items at Disney World. The Wikipedia entry cites the franchise and its characters but does not discuss retail or theme park product launches. Because the evidence is limited to a list of characters, we cannot infer a release cadence. For accurate information on merchandise releases, one would need to consult Disney World's official merchandise announcements, news releases, or the Disney Parks website. As of now, the available evidence does not provide a definitive answer.
