Coming mid next month, a new patch will be coming to Street Fighter X Tekken. This patch will include a variety of fixes, with the removal of an infinite combo glitch being one of the largest. Smaller items include the removal to hit crouching enemies during certain scenarios. Some other fixes are packed into this update as well. For a full list of fixes, head over to the Capcom Unity Blog.
Hopefully the game continues to be updated to prevent users from exploiting the game, as no one likes to get beaten into the ground by somebody using an unfair glitch or exploit.
