I know that it isn't a perfect solution, but if you read the text of the anouncement, it doesn't say that it will stop working on WI7, just that Genesys won't be fixing issues found etc.
I don't know for certain, but I suspect that a large part of this decision is based around the move towards Interaction Connect. Since this is Web-Based, the OS of the client is largely irellevant and this may offer an alternate path for people who want to stay with W7 until the end.
Yes, I accept that some parts of the product still rely on a native cleint running on the local machine, but with more and more people shifting to browser-based interfaces, this is, I suspect, going to become a non-issue for most customers.
