Yes, that is my current plan. This is my first attempt at a crowdfunding campaign, and one thing successful, experienced crowdfunders advised me against is offering physical rewards as a first timer.
The costs associated with producing physical rewards will suck funds out of a budget (regardless of size) like a black hole, so at this time I only feel safe offering digital rewards.
While I understand this news will be disappointing to some, I made this decision to safeguard the viability of this project.
