You did not misinterpret the page, but it seems that you encountered an out of the ordinary situation. Again, I would be happy to look into this if you sent me your details.
gdulli, Can't comment on what has happened up until this point, but if you are interested in having me dig into this to see what can be done email me at robert[dot]demmer[at]jetbrains[dot]com. Doesn't sound like our standard procedure.
Drop me a line with your dates, let me know if there's any particular team you would like to meet and what you would be interesting in seeing. robert(dot)demmer[at]jetbrains(dot)com
We are working on an interview with Andrei Ivanov, JetBrains Chief Operating Officer, that will likely answer this. For the time being, JetBrains was founded in 2000 in Prague by three software developers: Sergey Dmitriev, Valentin Kipiatkov, Eugene Belyaev. The headquarters and international sales office has remaining in Prague while the company continues to grow.
A: No. Android Studio and the Android plugin for IntelliJ IDEA are built from the same code, and all of the changes in Android Studio are, and will continue to be, available in IntelliJ IDEA releases.
Yep. IntelliJ is an IDE and Platform. In regards to ReSharper... stay tuned for an awesome upcoming webinar in February, ReSharper Secrets w/Igal Tabachnik. We will announce here in January: blogs.jetbrains.com/dotnet/
All functionality from the mentioned products would be available through IntelliJ IDEA plugins, however some features (really few non-essential) may be temporarily unavailable due to newer or older versions of the IntelliJ Platform. It is worth noting that the plug-ins are not sim-shipped though, so there is some delay.
Let me address now your specific situation as described above.
IntelliJ IDEA 13 will be released very soon. It will include the features from the recently released "smaller IDEs." Another point is that you do not need WebStorm. All WebStorm features are available in PyCharm and RubyMine or can be installed as plugins. Again, the plugins are not sim-shipped and will be available sometime after IntelliJ IDEA release.
To recap:
IntelliJ + plugins cover all functionality that all our IDEs provide. On the other hand, dedicated IDEs are convenient being more lightweight, offering a simpler UI and faster performance.
