The Zuberman quote, in the message above yours, pretty much answers your question.

1 Mobile Sheets will continue to be on offer, but with little or no further development other than bug fixes (not that it seems to have any).

2 A developed version (Mobile Sheets Pro) will be released, at some point in the future. This will incorporate many features that users have asked for (see other posts in the forum to find out what these are). MSPro will initially be discounted so that existing users may upgrade at a reduced price. After a period (one month?) the discount will cease and it will only be available at full price - it's really very cheap anyway.

Depending on your requirements, you may never need MSPro and what you have already paid for will be adequate - the existing version already caters for a lot of users. I certainly don't need it, although I will upgrade because I think Mike deserves the money .
