Well this surprised me! The Longhorn Engineer has plans to sell PCB's and kits I believe of a new 2600 motherboard! We still get the original TIA and its lovely sounds, with built in video mods (S-Video), controls and a nice screen. This will also alleviate the problems with faulty capacitors and such that have driven me crazy! My only worry is the quality of it's audio amp... I'm certainly excited to use this with music though! (it probably won't be compatible with Synthcart however because of it's limited controls)

Also the freaking Harmony Cart is out!!! I totally forgot about this one! Basically it's a nice 2600 flash cartridge with a built in SD card slot that supports SD and SDHC and USB built in. It support just about all of the 2600 library. I'm fairly certain it covers ALL titles regardless of their specific cartridge designs and such. The real kicker, it's only a whopping $60! Awesome!

So these are two great developments for Atari 2600 music!
