Project M (or competitive Smash in general) is nowhere near as big as you make it out to be. There are millions of people already sold on Smash 4's graphics or content alone. PM will have at most a 0.00001% dent in Smash 4's sales (especially because it's free).
You made those numbers up arbitrarily... I would argue that Project M is bigger than you think. If I can wear a Project: M shirt to a small college in South Carolina, and get comments fairly frequently from random people who see my shirt, unless my college is somehow an outlier (it isn't), then the game is pretty big. A LOT of people have played it. I know plenty of causal gamers, and semi-competitive gamers who know about P:M. And it is a mistake to assume that only competitive gamers play P:M, and a mistake to assume that only a competitive gamer would refrain from purchasing Sm4sh because of 3.5. Lets not forget that 3.5 is also adding tons of new costumes, stages, and single player features. Casual gamers would eat that content up.
I'm getting both because I'm a huge fan of Smash Bros in general.
And you can be assured that the PMDT knows exactly what they're doing. I seriously doubt something like this is going to hurt Nintendo's bottom line; we're an incredibly small niche in their demographic by comparison, which is probably why they gave zero ****s and set the release date when they did.
So, why in the hell are you raising a stink?

This comment was nicer before you edited it, lol. Before, you said I should trust them, and now you claim that they probably "gave zero ****s" about the release date. That's certainly not ok because we can't operate with certainty that this won't hurt sales, or our relationship with Nintendo, and how much they trust us with their IP.
I'm "raising a stink" because respecting Nintendo matters to me. Doing something like this could break our trust with Nintendo, regardless of whether or not it hurts sales. What do you think setting the release date so close to Sm4sh's release date says to them? Anything positive?
I'm also bringing this up because when sales haven't been going expectedly, Nintendo has made rash decisions in the past (remember when they started taking all ad revenue from YouTube videos using their games?). If sales for Sm4sh Wii U aren't that great for any reason, who is to say that Nintendo won't blame P:M? They wouldn't need proof for a C&D.
The only exception I can think of is if someone in the PMBR has talked with Nintendo staff and received an ok from them.
Finally, one last reason I am raising stick about this is because I have seen some toxic talk from the people on this forum in regard to other smash games. As a community, small or not, we should only have good things to say about the franchise in general, even if we don't like the current direction the games are headed in.
But a lot of the time, I just see neutral comments, or comments totally in opposition to any smash game released that isn't P:M. That isn't how this community needs to operate because, like I said, we are still dealing with Nintendo's IP.
