You are right — with hardware 2.2 it’s now easier to upgrade 644 to 1284, because Optiboot for 1284 already exists. At the moment we are not planning to upgrade to 1284 yet, partly because we still have existing stock of 644, and partly because the current firmware, which is 54KB in size, is not approaching the limit of the program memory size yet.
