Is Creative Suite 5.5 Coming Soon?

There have been a few mentions in the rumor-press about Adobe releasing Creative Suite 5.5 this year. For example, this AppleInsider article focuses on the Digital Publishing Solution facet of the Creative Suite, though it mentions that Adobe is focusing on EPUB in InDesign 5.5. A search for other instances of 5.5 leads to a French blog post about it (apparently Adobe Belgium accidentally included something about it on their site):

What the heck? Was that a leak or a typo? Actually, Adobe already announced that there would be a “dot release” of the Creative Suite which would include Acrobat X. Perhaps this is that coming release? Other Adobe sites haven’t mentioned it, but this livejournal post also points to a 5.5 with significant digital publishing features.

Given that CS5 came out less than a year ago, and given that Adobe usually follows an 18-24 month cycle for full releases (so CS6 should be due sometime between this autumn and next spring) it seems unlikely that any 5.5 product coming out soon would have a lot of changes — and if the main change is adding Acrobat X, it would be a hard sell to most InDesign users. However, that won’t stop me from wishing on a star for about 50 features I would like to see in InDesign. I guess we’ll have to wait and see…
