Is MSP[432] right platform for my ideas?

Hi folks,

I wish to create (and market) series of open source projects that will include both mechanical and electronic / microcontroller components. While electronics periphery and mechanics will change from product to product, software will gradually evolve with each project. For example my first project is a modern rotary head/platform controller that can be used for manual machining, 3D Scanning and any other application that requires 1-2 axis motion. With limited G-Code support and few external connections.

My vision are modern, state of the art devices that might have such features as build in graphic displays (possibly touch), network connectivity, web configuration and control interfaces. Power consumption will not be a issue since all projects I plan have utility power.

My Assembly and C days are about 20 years away, in this millennia I have mostly done UNIX sysadmin and web development stuff. So I enter microcontroller world as a newbie but not completely naked.

I am on the crossroads now as to which hardware / microcontroller to chose.

A combination of SBC with slave MCU?
Would probably give best flexibility, performance and speed up development but somehow it feels like overkill and is relatively expensive hardware wise, especially if I wish to market the devices.

Atmel?
Has a great community and huge amount of code and projects but quite centered around high level arduino IDE and many projects are licensed under GPL while I prefer MIT / BSD.

TI / MSP?
Seems to me like a smaller community but more low level oriented, I read several chapters from 'MSP430 Microcontroller Basics' and so far liked it.

Brand new MSP432P401R Launchpad seems like excellent base to build upon with enough power(?) and connections to fit all my ideas.

What do you think? If you where to enter the microcontroller world today with projects I outlined above, would you chose MSP or something else?

Thanks
