TI bringing new, high-end LaunchPad to the table.

Found on TI's wiki page for their "Hercules" processors, which are ARM Cortex RM4(F) and RM5F based and oriented at deterministic, real-time control; scroll to the bottom of that page and look for the "LAUNCHXL2-570LC43" device and you should see the following link: LAUNCHXL2-570LC43
There are actually two coming out, but both processors are pin compatible and have different "ratings" and both use the same circuit board. One processor, RM57L843 is certified for industrial / medical use and runs at up to 330MHz, while the other TMS570LC4357 is certified for automotive use and runs at up to 300MHz. ECC features cover most every aspect of the architecture, as well.
I think the claim regarding 'deterministic, real-time' control refers to knowing how long it will take before an interrupt request handler is instantiated, leaving it up to the system engineer(s) and programmer(s) to actually ensure things are handled as scheduled. However, the in-built peripherals can run nearly autonomously once configured, and can use DMA to transfer values between themselves, including things like an ADC conversion can trigger a DMA transfer to the SPI peripheral without core processor interdiction.
Another feature of these is their N2HET peripherals, which are VLIW processors that can do precision timing related things such as PWM for 3-phase motor control and precision shaft angle detection. If you're familiar with Freescale devices and the TPU / eTPU, this is analogous to those.
Formal announcement of this should be made around June 10, 2015, so consider this a head's up.
