TBH, PGMusic does offer deep discounts once a year and it is worth getting it while on sale.
However, get the version you are comfortable with price wise.

I'd suggest not missing out on the lower prices this time of year.
It will go up, exactly when is unknown, but the time to take the plunge is while it is on sale during the new release (like now)..

I do not work here, but the benefits are still awesome
