All good questions. First, if you haven't read the white paper, FAQs, and watched the videos on https://eos.io/ I would highly recommend you start there.

The description of the ICO is explicit in which they state the token has no value and is effectively used to raise funds. However, I believe this is an attempt to be as politically correct as possible in an attempt to not represent the tokens as any type of currency. As we all know this does not let anyone off the hook regardless of their use of words when it comes to an ICO. In researching EOS, various sources will lead you to believe that the EOS tokens (as called for the ICO) will be frozen at the end of the ICO and EOS coins will be issued. It was made clear that developement for the EOS coin developement will not be a responsibility of block.one but will be open source. The general intent is that the "coin" is and asset in controlling a portion of the EOS platform bandwidth... and play into voting rights. Again, I would refer you to the white paper and EOS website for more info on this.

Now, I could never do it justice in terms of the technical explainations that Dan Larimer gives on the overall architect but as a "supporter" this is how I envision this product...

The investment in the current EOS tokens will be converted to EOS coins. The tokens on the Etherium blockchain are abandoned... ETH loses value even more. The new EOS coins are utilized and scaled to allow access to the "bandwidth" of this decentralized network. All new Dapps and companies that have began backing the product are ready to go live or have been already created their products during this ICO/development phase. On a grand scale you as an ICO supporter own resources that all of these companies are wanting to utilize. Not sure if I can put a dollar amount on that.

Again, this is my humble opinion and nothing is a guarantee but my guts tells me this will be huge!

I would also take a look at this for progress on the development front... posted just a while ago https://steemit.com/eosdev/@dan/eos-development-sneak-peek-for-very-early-developers
