Over the coming weeks people started doing other calculations trying to guess the performance of the machine - don't forget that this is a long time before development kits were available to do actual tests. Some people even built custom PC rigs with under-clocked CPUs to try and gauge performance of their code on these machine. Again, the almost universal answer was that it wasn't going to be powerful enough to run next-gen engines and it might even struggle to do current-gen (PS3 and X360) titles. But in spite of these tests the management made the decision, for various business reasons, to release a game on the Wii U. So now we had to get stuck in and try to make a game.
Damn, now you hear it from a 3rd party.
