<human>: Give me the gist of the text in a nutshell

I didn't know where else to get advice from but here, since people here always give good advice. 

Okay, I have this Marketing project for one of my classes (due in May). We have to come up with a new product and introduce it to a different country outside of the USA. At first my group was progressing well and then we had snow 3 times in two weeks (which NEVER happens down south) so we got behind on working on our project. 

We've only been corresponding through texts and the 5 minutes before and after class. This week we finally began working on the project again. I sent around a mass text to the group members that we need to finalize the name, design, colors, price of our product (a soda). I finally get a message back , 3 days later, that says "Product name and design aren't important, we'll do those last". I look at the text with a WTF look on my face because I thought it made no sense. How can you begin to market something without even knowing what the hell it is? I haven't replied to her because I don't know how to phrase my concern without sounding like a dick. 

Ive had projects extremely similar to this in high school, so I know how much you need your product finalized in order to accurately promote it. 

So my questions are:
1. Am I wrong that we need an actual finished product before we begin trying to market it?

2. How do I phrase my concern without sounding bitchy?

3. Should I just drop the group and do a solo project?
<bot>: group leader wants to come up with a marketing plan for a product that doesn't even exist yet, and I think we need to finish creating the product first. How do I voice my concerns?
