I thought they were competing in the same space and were further ahead, too. But having read those articles, I think no. From the second articlet:

Crossbar does not position its ReRAM as an alternative to technologies such as flash-based solid-state drives (SSDs). The initial use cases for ReRAM will more likely be under the covers in CPUs, field programmable gate arrays (FPGAs), and system-on-a-chip (SoC) architectures, possibly as an alternative to slower static RAM (SRAM) or less energy-efficient dynamic RAM (DRAM), according to Sylvain Dubois, vice president of business development and marketing at Crossbar.

In contrast: here's a quote lifted straight from Weebit's web page:

Resistive Random-Access-Memory (ReRAM) is the most promising technology to replace Flash.

So ... Crossbar aren't looking to replace flash. Weebit are. That's a huge plus for Weebit, in my book.
