pdb1: What I do not think will happen . Is that mobile play will replace PC / laptop play .
I have to completely agree with this.
While gaming may be embracing mobile devices, they're not going to give up on the PC platform where that already is in place and they have a customer base. In this case, the other examples of one technology replacing another are not analogous. The mobile platform will supplement the PC (or possibly, at some point, the other way around); but it will not supplant it.
For the foreseeable future, there will be a market for PCs. And as long as there is, there will be a demand for this game in that platform.
