Yep, as anyone knows by now, AVR is a Microchip property. Not yet a product... will see about this later. Anyway, first effect: Pickit2 programmer is no longer restricted in programming AVR microcontrollers (this means a common ICSP connector for development boards addressed to usual PIC programmers willing to try AVR). Also, we expect a better availability and maybe low prices for ATmega and ATtiny microcontrollers.
See the Microchip declaration here.
