It depends how you think. If you only think that you will do piracy once your Wii U is released, then you have no respect for video games, and you are a horrible person. If you want to try some new games you are not sure of buying, but you keep buying games you are eagerly waiting for, then yes, you deserve that exploit.
If everyone does piracy, then video games will cease to exist in a mere months. Think about that.
I love the fact that I can try some new games, which I would never buy otherwise, but I bought a Wii U two months ago, and I already bought Xenoblade Chronicles X and Splatoon. And i'll keep encouraging industry in that sense.
