From where I am sat working on first party PS3 stuff it seems to be going the other way. To be effective at my job I need to have a high level of skill with a wider range of packages and bespoke tools than ever before.
Seems to me like every time the tools reach a point of maturity such that Joe public can effectively use them, the technology moves on a significant leap, meaning that a lot of your old skills are now redundant. Only your experience can be said to be truely transferable.
