The introductory upgrade price of $89 will end June 30, 2016. After that, the cost to upgrade from Sibelius 1–7.5 to Sibelius 8 will be $299 – a discount of $300.
This reads as desperation to me, especially juts a few weeks removed from the deafening buzz surrounding Steinberg’s Dorico announcement.
