GP4 was announce long before the sale, yes. And I didn't expect it to get the upgrade for cheap, mind you. What I didn't expect was that GP4 will cost the same whether you've bought GP3 or not. Again, the upgrade from the free Ampeg amp costs the same.
What I expected when they did the sale was that, at worst, It'll cost exactly the same as buying the new version outright. Not more. When I say "money down the drain" I meant that if you want the new version you'll pay $99 for it whether you bought GP3 or not. English is not my mother tongue, so is probably my fault and I'm making a mess of words. My apologies.
Of course I can use it! And I intend to do so.
GP4 is $99 right now. Not $169. To most people, at least. I mean, maybe some people don't qualify for the upgrade... but considering a free amp gives you access to the update, I'm betting most qualify.
I paid $39.99 for it, almost half of what the new version costs. So the new version costs $140 for me instead of the $100 that it costs for (almost) everyone. What I'm saying is, if you were interested in the newer version, not buying on the last sale (which, I might add, they did 16 days prior to the launch of the newer one while having a 14-day refund policy) would have been cheaper.
I'm not saying they should give it for free; quite the contrary. But charging the same for the upgrade to people that bought the previous version as for people that didn't right after doing a big sale is... well, it's not nice.
