i think they might've meant it will be as successful as Harry Potter

Yes, i agree. Everyone seems to take offence at SB being compared to HP, but I believe they only mean that there are several books in both series and both are successful. What is to complain about if Alex Rider is as big a hit as Harry Potter? I really don't think that anyone is making a correlation between the worlds of AR and HP. They ARE completely different.
I for one hope the whole world embraces the AR series as much as they have HP!
