I have looked for about 15 minutes but couldn't find any info on this topic yet. I noticed this morning in the tech specs for the AT4 that it outputs at 1080p at 60fps. I then went and looked under the ATV3 and saw that it maxed out at 30. If you look under "compare", it only says 1080p for both. but looking under the individual items lists the fps. Im surprised this hasn't been brought up yet, because to me this is a huge upgrade. That along with the processor upgrade justifies most of the upgrade cost to me. Im sorry if this has already been brought up.. my search skillz are not always wonderful.
