Launch price of OS updates

[Socratic]

I know nothing is announced for Lion.
The upgrade for Snow Leopard is currently £26 on the UK store. I'm just wondering if it's typically around this price at launch, or if they launch at a high price then drop?

There really is no upgrade price with Apple, Mac OS X 10.4 Tiger and Mac OS X 10.5 Leopard each cost 129 USD, regardless of what previous OS you have. Mac OS X 10.6 Snow Leopard was just 29 USD as it was more of a "Service Pack", as most of the changes have been under the hood and not the fancy schmancy one expects from a new OS.
Therefore it is safe to assume that Mac OS X 10.7 Lion will cost more than 29 USD, it even might cost less than 129 USD and be around 70 to 80 USD.
