Well, I do understand what you mean, but I failed to fully express my point.
I'm far from an x2 fanboi. Frankly I think Uber is a dick, and always has been a dick in any contact I've had with him. Aside from that, you have to respect what the x2 team has contributed to the scene.
That being noted. The current bios, including the ftp.. The only updated feature on said bios, is the ftpd. So I am guessing, that x2 will show the scene support they have since day 1, and when there are other features aside from the ftpd embedded into the bios, if they could fit into a 256k bios would be done, sans the ftpd. So you'd end up with x2_4999_FTPD.bin(512k+) AND x2_4999_NOFTPD.bin(256k). Again, this is a guess, but it's based on the example of support the x2 team has displayed to date. And again, this assumes additional features will fit in the existing 256k space available to them.
Currently, however. There is no reason to have 2 releases of the current bios, one with ftpd and one without, because the only difference between this version and the previous stable release is that said ftpd. To release a version of this build sans ftpd, would just be cloning the previous stable build.
My opinions aren't based on fact, more assumption. But it seems to make sense to me based on the previous support the x2 team has given the scene.
