We don't know. Maybe even Intel doesn't know. Furthermore, it is very unlikely to be 2 months, from the info provided/leaked so far, it seems that Broadwell-E/Broadwell-EP are the first CPUs to have fixed TSX again, and Haswell-E has only been released a month ago. Note, Haswell-E usually seems to have TSX disabled already in BIOS, so microcode_ctl doesn't do anything regarding TSX there.
