content: Damn, $200 is pretty pricey. My $12 dev board is enough horsepower for what I do regularly.

content: I guess with this price compared to their low priced Launchpad series with lower power mcu, this is targeted for pro ?Just look at board and those connectors.

content: A friend of mine who's a TI FAE mentioned a new (much less expensive) dev kit is coming out for this chip soon.

content: It needs to be a whole lot cheaper. TheSTM32 F429 Discoveryalso uses a Cortex-M4F based uC, which runs at 180 Mhz and offers close to the same functions, sells for less than $40.

content: Its quite common to have a small (cheap) board for the masses & a more advanced one. Same with the F429, the STM32429I-EVAL goes for like $400.But I wonder when the new TM4C129x’s become available, TI made quite a few people “unhappy” by suddenly putting the Luminary Micro chips NRND without being able to supply some sort of replacement.

content: Is there much of a market for this sort of board these days?Years ago, getting a board with a bunch of stuff on it was often useful to try out some ideas because getting a decent board fabbed was a large outlay.Now you can get a decent sized two and four layer board very cheap. If I want to try something out I'm either going to go real quick and cheap and just use something like the launchpad/disco board with some sort of proto board, or I'm going to quickly get a board made with the actual peripherals I want on it. Or do they just make this as sort of a "reference design"? I've certainly looked up the schematics of dev boards before to see how they've gone about some part of it.Or perhaps is this targeted at the education market?

Usually the software development team can start learning the SDK and doing GUI stuff while hardware developers are busy hashing out other aspects of the board. That and the fact you are sure the hardware is working, which helps identify the origin to solve the usual "HW/SW bickering"...
