Anything and everything is considered when a beta is opened. We read all suggestions and prioritize from there.
On a personal note though 2Checkout is very small considered next to Paypal which is huge and we do have in our supported list of processors.

Almost half that of 2Checkout for the percentage taken each transaction.
