not really, CS5 is 4 years old and they have released CS6 and changed to the CC format now. If I worked for Adobe I wouldn't be updating old software to work with brand new systems when my newer software already does the job.
You are right from Adobe standpoint. But I would like company like Windows still update Win XP untill this year that launch at 2001 although Windows already launch vista, win7 and win8.
