This is not a bait and switch. We are trying to make sure we get the pricing right. That said - we plan to make the current free tier free even when we announce pricing. We are also committed to being competitive in terms of pricing. We will be announcing pricing this summer.
But you've "announced" your cloud platform, yet I can't justify any time learning or becoming familiar with it since there is no idea on price - it's frustrating.
Does the other cloud providers seem reasonable to you? If so then you might want to spend time investigating. As a dev evangelist for OpenShift, I can say it doesn't take much time to get a simple app up and running. Come by #openshift on freenode and we can help you if you get stuck
No they don't - that's my point (Only AppEngine did before they increased their prices). Because of the high cost of available clouds I don't use any clouds and just run my own dedicated server.
