You got some weird bones...
As it happens, I do!
I've seen quite a few adverts now for cut-price Macs from various locations here in the UK. It seems to me that Apple and the retailers are aware that their products are no longer competitive and are trying to keep sales going with discounts. I expect they can do that for a while unfortunately. A lot of people will be unaware of the fact that an update is due and buy anyway. It's no real skin off Apple's nose to capitalise on it either.
I really do expect the new models to be announced some time this month though. I don't see them waiting until June at any rate. That would be virtually suicidal given the competition.
