I think Intel will announce an acquisition of Achronix at some point (if things work well with this deal).
At 22nm and below, one needs very high volumes to be successful... FPGAs could form one such business. I think Intel wants to get into the FPGA space, especially since many of the basic FPGA patents from the 1980s have expired. Its one of the few businesses in semiconductors with similar gross margins to Intel's x86 business.
Instead of building a FPGA team within Intel, Intel is probably trying to get into the FPGA business through the Achronix team. Its not an easy road though... Achronix is a startup without enough volume, they will lose a lot of money trying to build products at 22nm and below due to high NRE costs (till they get enough customers and break-even)
Note though, that this is all speculation on my part!!!
Intel is clearly testing the waters with this deal. I am not sure Achronix business is of interest to Intel, but it's a good guinea pig to test their 22nm technology as well as the foundry model especially with the extra capacity Intel has at the moment.
Intel needs a vehicle to test their 22nm process before CPU and FPGA (Other than Xilinx and Altera) is a good candidate for them. If successful, it's good for both Intel and Achronix. But Can Intel supply a volume to Achronix? Waiting to be seen....
