Oracle cares about one thing only...
These are sad days indeed. The problem is that Oracle cares about revenue above anything else, which (in my very personal and humble opinion) includes customer happiness. Sounds crazy, but just look at all the evidence around you.
When they took over support costs immediately went through the roof while you basically got much less in return (for starters no more access to SunSolve; one huge knowledge base which had pretty much background info on *anything* Sun had made and/or supported). That place was amazing. Trouble with your (6 year old) Blade server? No problem: full specs plus instructions on how to take it apart were all available. But after the takeover you could forget about all that.
I've said this for quite a while already, even though it honestly saddens me, but people who are still using a licensed version of Solaris are much better off with looking for alternatives. The most obvious alternative is of course OpenIndia or Illumos, the open source Solaris version which isn't fully controlled by Oracle (and therefor can't be shut down on a whim, which happened with OpenSolaris).
Another solid alternative is FreeBSD. Solaris is a direct descendant of a true Unix environment, AT&T's Unix Sys V to be precise. FreeBSD has its roots into Research Unix through BSD (Berkeley Software Distribution). But what makes FreeBSD a true replacement for me is because it supports everything which made Solaris great. DTRace or ZFS? Not only does FreeBSD fully support those (you can nowadays even have your root filesystem fully on ZFS without issues), the origin of some of these features comes directly from Sun Microsystems who at one point helped the BSD project with porting these over.
Even from a licensing perspective will you find that FreeBSD has much more in common with Solaris and the vision and ideas behind it, than others. You can get commercial support for FreeBSD if you need it, but you'll soon learn that you'll come across companies (and people behind those companies) who care for the operating system and your happiness over money. Sure: a SLA is a SLA and that has to be honored on both ends. But you'll have much less risk to be talked into something which in the end will only cost you more money while your benefits are slim at best.
Solaris really is at its end. You may think that the "continued support" sounds like a good thing but trust me: it isn't. They don't do that to make your life easier, they do that to reduce their own overhead costs as much as possible. Instead of sorting out an update which specifically meets certain demands and/or standards (like making sure you separate between optional and required updates) they'll now simply throw everything together and release it. Then it's up to you, their "valued" customer, to sort it all out.
And if it doesn't work? No worries: I'm sure that for only E 1500,- / month extra you can get on-hands telephone support but only during business hours and limited to those questions which apply to the continues upgrade process.
